Portugal is facing severe disruption to transport, flights, hospitals, schools and other public services on Thursday, as the two main union federations stage a general strike over unprecedented labour reforms.

The last time the CGTP and the generally less militant UGT joined forces was during the eurozone debt crisis in 2013, when a "troika" of international institutions demanded cuts in salaries and pensions as part of Portugal's bailout.

Twelve years later, Portugal's economy has become the fastest growing in the eurozone in recent months, but Prime Minister Luís Montenegro says it is still necessary to tackle "rigidities" in the labour market "so companies can be more profitable and workers have better salaries" as a result.

"I will not give up on having a country with the ambition to be at the forefront, to be at the vanguard of Europe," he said on the eve of the strike.

However, Montenegro appears to have been taken aback by the strength of feeling against his minority right-of-centre government's plans: one of his Social Democrat MPs is on the UGT executive and even he voted for a strike.

The prime minister tweaked some proposals after calling the federation in for talks late last month, but it was clearly not enough.

Among the most controversial of the more than 100 proposals are:

• letting employers roll over temporary contracts for years on end
• lifting a ban on sacking workers then immediately rehiring them indirectly via outsourcing
• removing a requirement to reinstate employees who were unfairly dismissed.

It is Portuguese in their 20s who are likely to be most affected by the changes - and opinion is rather mixed.

Diogo Brito, who works as an air steward but has friends who do casual work in tourism, supports the right to strike but backs the package: "It has to be done. We have to catch up with richer countries and with these measures I think we can evolve more."

But self-employed photographer Eduardo Ferreira says he knows many people who already cannot find secure jobs and is pleased to see the unions unite at a "critical moment" for Portugal: "Things have been tough ever since the troika, and workers haven't reacted until now."

The CGTP has condemned the package as "an assault on the rights of all workers, particularly women and young people", while the UGT calls it "so out of step, in a context of economic growth, financial stability and a strong labour market, that… it reflects a clear bias in favour of employers".

The UGT also complains that formal talks between unions, government and business were "unbalanced, restrictive and detrimental to workers".

Montenegro's governing coalition lacks a majority in parliament, and is seeking support for the bill not only from the small, free-market Liberal Initiative (IL) but from hard-right Chega, which since May's general election has been the second-largest party.

Its leader, André Ventura, has expressed reservations about the way some measures might affect family life, but looks open to negotiations.

Before the election, Montenegro had ruled out deals with Chega, and the unions and the third-biggest party, the Socialists, say the prime minister's mask has slipped.

They also warn that politicians on the right want to amend Portugal's 1976 constitution to loosen employment safeguards considered among Europe's strongest.

The issue has also become caught up in the campaign for January's presidential election, with several candidates arguing that the labour reform bill flouts Portugal's 1976 constitution.

Under Portugal's "semi-presidential" system, the head of state can decline to sign bills approved by parliament. Bills can instead be sent to the Constitutional Court for review or the president can exercise a veto that, while it can be overturned by a majority of elected MPs, delays the process, ensuring further discussion.

With the government seeking to overhaul so much of the labour code, such scrutiny might stoke voter unease about its radicalism, particularly since the plans were not in the coalition's election manifesto.

Unlike many strikes here, Thursday's day of action is not limited to the public sector.

At Portugal's largest factory, VW-owned Autoeuropa, south of Lisbon, almost 1,000 employees voted unanimously last week to back it.

"I believe there is no worker in this country unaffected by the negative measures in this reform," said UGT secretary-general Mário Mourão, after the Autoeuropa gathering. "It must be responded to appropriately."

In a matter of days, three big names in South Korea's entertainment industry have made headlines in separate scandals that could derail their careers.

The allegations that have embroiled comedians Park Na-rae and Cho Sae-ho, as well as veteran actor Cho Jin-woong, are all different - ranging from workplace abuse to previous teenage detention to associations with a gang member.

But the results have been the same: departures from the television screens where they had worked their way up to become household names.

The scandals have also raised questions about the standards to which South Korea's public figures are held - especially in the entertainment industry.

What are the scandals about?

Park Na-rae, one of the country's most successful female comedians, made headlines last week when two of her former managers lodged criminal complaints claiming she had verbally abused and physically assaulted them.

The 40-year-old had also made them do her personal chores, they alleged.

Park has denied these allegations and sued the former managers for blackmail, her agency said over the weekend.

She is separately being accused of receiving IV drips illegally at home, which violates the local medical law, local media reported - prompting a police investigation.

On Monday, Park Na-rae announced on social media that she had talked things through with her accusers, but would halt all broadcasting activities until things were "clearly resolved".

"As a comedian whose job is to bring laughter and joy, I cannot continue to be a burden to my programmes and colleagues," she wrote on social media.

Another comedian who has come under scrutiny over the past week is Cho Sae-ho.

Rumours started swirling last week that the 43-year-old was friends with a prominent local gang member and had received money to promote the latter's business.

Backlash came swiftly, as social media users demanded that Cho Sae-ho be removed from the popular variety shows he hosted, You Quiz on the Block and Two Days and One Night.

On Tuesday, Cho Sae-ho's agency announced that he would leave the shows - though it denied his links to the gang's business activities.

In a social media statement, Cho Sae-ho said he "should have been more careful" with the people he met at events.

He added that he had decided to step down from the shows because he did not want to "burden" the programmes and their production teams.

The downfall that has generated the most debate comes from veteran actor Cho Jin-woong, who said over the weekend that he would quit acting.

The abrupt announcement came after a viral news report that said Cho Jin-woong, as a teenager in the 1990s, had been sent to a juvenile detention centre on allegations of robbery and sexual assault. As an adult, he also assaulted a person in his theatre troupe and had his driving licence suspended for drink driving, the report said.

The 49-year-old's agency said that Cho Jin-woong had confirmed wrongdoing in his youth, but denied sexually assaulting anyone.

Broadcasters have scrambled to erase Cho Jin-woong from their platforms. A documentary series he narrated has now had the narration re-recorded, while the fate of Second Signal, the sequel to his hit TV series, remains unclear.

A debate over cancel culture

The allegations Cho Jin-woong faces have stirred heated debate about how much public figures should be forgiven for past mistakes.

"Why does Cho Jin-woong need to retire?" reads one social media comment. "Why should a flawed past remain the standard by which a person is judged decades later?"

Others, however, have argued that seeing him on screen could retraumatise his past victims.

"There are people who defend [Cho Jin-woong] by saying everyone makes mistakes when they're young, but not everyone commits this level of crime," wrote one social media user.

More broadly, the recent string of celebrity scandals has raised bigger questions about the standards to which South Koreans hold their celebrities. It's a system that has sent rising stars into hiatus for being school bullies, and squeezed apologies out of them for simply dating other celebrities.

Culture critic Kim Sung-soo tells the BBC that in South Korea, audiences want to correct behaviour that they deem unacceptable - which, in the case of celebrities, often means disappearing from the screens.

"Celebrities are easy targets because their careers depend on reputation and popularity - things that are granted by the public," culture critic Kim Sung-soo tells the BBC.

Now, just as Park, Cho Sae-ho and Cho Jin-woong promised to "reflect deeply" on their actions, it appears some among their audiences are also reflecting on how celebrities are treated.

"It's absurd that people mistake this recurring pattern of targeting celebrities online - digging for flaws and pushing them out - as a moral issue," one person wrote on X.

"I'm tired of this cancel-culture cycle, and I think it's time for our society to seriously rethink online communities."

Shares of cloud computing giant Oracle plunged more than 10% in after-hours trading on Wednesday after the company's revenue results fell short of Wall Street expectations.

The company reported revenue of $16.06bn (£11.99bn) for the three months that ended in November, compared with the $16.21bn projected by analysts.

Revenue growth was up 14%, with a 68% surge in sales at its AI business, Oracle Cloud Infrastructure (OCI), the company said.

OCI services major AI technology developers whose demand for Oracle's AI infrastructure helped the company's shares reach new highs this fall but Wednesday's results failed to quell fears about a potential AI bubble.

In September, Oracle inked a highly sought-after contract with ChatGPT-maker OpenAI which agreed to purchase $300bn (£224bn) in computing power from Oracle over five years.

Oracle chairman and chief technology officer Larry Ellison briefly became the world's richest man.

Oracle stock has lost forty percent of its value since peaking three months ago. Still, shares are up more than 30% since the start of the year.

In a statement issued Wednesday, Mr Ellison struck a cautious tone.

"There are going to be a lot of changes in AI technology over the next few years and we must remain agile in response to those changes," Mr Ellison wrote.

Mr Ellison also appeared to snub Nvidia, the designer of highly-sophisticated AI chips, saying Oracle would buy chips from any maker in order to serve clients.

"We will continue to buy the latest GPUs from Nvidia, but we need to be prepared and able to deploy whatever chips our customers want to buy," Mr Ellison declared in a policy he called "chip neutrality".

Oracle is involved in multiple AI infrastructure arrangements that have raised the prospect that major players in the sector are participating in 'circular financing' deals whereby companies finance purchases of their own products and services.

"Oracle's earnings arrive as investors weigh whether its massive OpenAI partnership might mean overexposure with a customer currently in the spotlight over profitability concerns," said Emarketer analyst Jacob Bourne following the release of the company's quarterly report.

Bourne said Oracle faced mounting scrutiny over the increased debt the company has amassed to fund its buildout of data centres.

Oracle raised a record $18bn (£13.4) in a massive bond sale in September, one of the largest debt issuances ever in the tech sector.

"Although Oracle's shares are buoyed by its September surge, this revenue miss will likely exacerbate concerns among already cautious investors about its OpenAI deal and its aggressive AI spending," Mr Bourne said.

The Ellison family, supporters of US President Donald Trump, also recently purchased Paramount and have spearheaded a failed bid to take over another major Hollywood studio, Warner Brothers Discovery.

European leaders say "intensive work" will continue in the coming days on a US-led plan to end the Russia-Ukraine war, after a joint phone call with President Donald Trump.

UK Prime Minister Sir Keir Starmer, French President Emmanuel Macron and German Chancellor Friedrich Merz said they "agreed that this was a critical moment - for Ukraine, its people and for shared security across the Euro-Atlantic region".

A White House official confirmed the call took place but did not give details.

It comes the day after Trump called European leaders "weak", suggesting the US could scale back support for Ukraine.

In the wide-ranging Politico interview published on Tuesday, Trump also claimed Ukraine was "using war" to avoid holding elections, prompting President Volodymyr Zelensky to reply he was "ready" for them.

Russian President Vladimir Putin launched a full-scale invasion of Ukraine in February 2022, and Moscow currently controls about 20% of Ukrainian territory.

The three European leaders issued identical statements shortly after their call with Trump on Wednesday.

They read: "The leaders discussed the latest on the ongoing US-led peace talks, welcoming their efforts to achieve a just and lasting peace for Ukraine, and to see an end to the killing.

"Intensive work on the peace plan is continuing and will continue in the coming days."

Earlier on Wednesday, Zelensky wrote on social media that a 20-point document on how to end the war would be handed over to the US in "the near future" after "our joint work with President Trump's team and partners in Europe".

The Ukrainian leader provided no further details.

The original US draft peace plan - widely leaked to media last month - had 28 points, and was seen as favouring Russia. Ukraine has since held separate talks with US and European negotiators, seeking to change some key clauses such as territorial issues and security guarantees.

Zelensky is under increasing pressure from Trump to agree to a peace deal to end the war, with the US president urging Kyiv to "play ball" by ceding territory to Moscow.

Zelensky has repeatedly refused to do so, seeking instead an immediate ceasefire on the vast front line and iron-clad security guarantees for Kyiv in any future settlement.

The Ukrainian leader is on a diplomatic tour of Europe following intensive talks between US and Ukrainian negotiators over the weekend which failed to produce a deal to which Kyiv could agree.

Zelensky has been pressing his European allies to help deter the US from backing an agreement that could leave Ukraine exposed to future attacks by Russia.

Meanwhile, the Kremlin said Trump's "very important" statements on Ukraine, including saying Moscow would win the war and that Kyiv would need to hand over land, align with Russia's view.

"In many ways, on the subject of Nato membership, on the subject of territories, on the subjects of how Ukraine is losing land, it is in tune with our understanding," Putin's spokesman Dmitry Peskov said.

Last week, Putin repeated his warning that Ukrainian troops must completely withdraw from Ukraine's eastern Donbas region or Russia will seize it, rejecting any compromise over how to end the war.

Italian cooking has been awarded special cultural heritage status by the United Nations' cultural agency Unesco.

National favourites including pizza are already on Unesco's list of "intangible cultural heritage", but now Italian cooking traditions and the way they are practiced and transmitted have been awarded.

Prime Minister Giorgia Meloni, who has been pushing for her country's cuisine to be recognised since her election, said: "For us Italians, cuisine is not just food or a collection of recipes. It is so much more: it is culture, tradition, work, wealth."

For millions of fans the news confirms what they already believed - from Sicilian Cannoli to Calabrian 'Nduja - Italian is the best.

The announcement was made during a Unesco assembly meeting in the Indian capital Delhi on Wednesday.

The cultural agency described Italian cuisine as a "means of connecting with family and the community, whether at home, in schools, or through festivals, ceremonies and social gatherings".

Koshary, the spicy dish of lentils, rice, and pasta available at countless Egyptian food stalls, was also added to the list of intangible cultural heritage.

Other countries have had their "practices, skills, traditions and social practices related to foodways" recognised by Unesco, a spokesperson from the agency told the BBC.

Previous examples include "Washoku, traditional dietary cultures of the Japanese, notably for the celebration of New Year, Breakfast culture in Malaysia: dining experience in a multi-ethnic society, or the Gastronomic meal of the French," the spokesperson added.

Speaking to La Repubblica, the Rome-based daily newspaper, chef Michelangelo Mammoliti said the news filled him with a great sense of pride both personally as an Italian, as well as professionally as a chef.

"Italy is one of the nations where regional cuisine has a very big impact on culture and traditions," said the chef, whose restaurant La Rei Natura in Piedmont is the only new three-star restaurant in the 2026 Michelin Guide.

Italy's industry leaders and government ministers will be hoping that the move further boosts tourism to the country, which already welcomes 80 million international visitors annually.

Luigi Scordamaglia, CEO of Filiera Italia, which represents all the food and wine companies in the production chain, told Ansa news agency that the move from Unesco marked a success "for the entire Made in Italy supply chain".

Mr Scordamaglia also spoke about the role of the Mediterranean diet in promoting good health.

He added: "When we talk about the Mediterranean diet, we're talking about our wonderful Italian cuisine, which shares its principles, first and foremost those of balance and variety."

Swimming pool culture in Iceland; the practice of Cuban Son music and dance; and the art of playing, singing and making the lahuta from Albania also entered Unesco's list of intangible cultural heritage.

A senior government official in Benin has told the BBC that the leader of Sunday's failed coup is taking refuge in neighbouring Togo.

Speaking on condition of anonymity, the official said that the government would request Lt Col Pascal Tigri's extradition. Togo's government has not yet commented.

The failed coup came after a series of military takeovers in West Africa, raising concern that democracy is increasingly under threat in the region.

It was thwarted after regional power Nigeria sent fighter jets to dislodge the mutineers from a military base and the offices of state TV following a request from President Patrice Talon's government.

A group of soldiers appeared on state TV early on Sunday to announce they had seized power, and gunfire was heard near the presidential residence.

The Beninese government official said the authorities knew that Lt Col Pascal Tigri was in Togo's capital, Lomé, in the same area where President Faure Gnassingbé lives.

"We don't know how to explain this but we will make an official extradition request and see how the Togolese authorities will react," the official added.

There is no independent confirmation of the claim.

French special forces also helped loyalist troops to thwart the coup, the head of the Benin's republican guard, which is in charge of protecting the president, told AFP news agency.

Dieudonne Djimon Tevoedjre said Benin's troops were "truly valiant and faced the enemy all day" on Sunday.

"French special forces were sent from [Ivory Coast's main city] Abidjan, used for mopping up operations after the Beninese army had done the job," he was quoted as saying.

Benin's government spokesman Wilfried Léandre Houngbédji could not confirm the deployment of French forces.

He told the BBC that as far as he knew, France had mainly provided intelligence support.

Togo is part of the West African regional bloc, Ecowas, which condemned the coup attempt.

Ecowas has deployed troops from Nigeria, Ghana, Sierra Leone, and Ivory Coast to secure key installations in Benin.

The deployment signals that Ecowas is no longer willing to watch civilian governments fall without resistance.

Benin, a former French colony, has been regarded as one of Africa's more stable democracies.

The nation is one of the continent's largest cotton producers, but ranks among the world's poorest countries.

Nigeria described the coup attempt as a "direct assault on democracy".

Houngbédji told the BBC that a small number of soldiers from the National Guard were behind the coup attempt.

"The National Guard is a recent creation within our army, initiated by President Talon as part of our fight against terrorism. It is a land forces unit equipped with significant resources, following major investments in recent years, and its personnel are well trained," he said.

Houngbédji added that Talon asked Ecowas to carry out airstrikes to neutralise the mutineers following indications that they had planned to attack the main airport in Cotonou, Benin's largest city, putting at risk the lives of civilians living in the area.

"This led to the strategy of carrying out targeted airstrikes to immobilise their equipment, including the armored vehicles they threatened to use," he said.

The rebel soldiers justified their actions by criticising Talon's management of the country, complaining first about his handling of the "continuing deterioration of the security situation in northern Benin".

Benin's army has suffered losses near its northern border with insurgency-hit Niger and Burkina Faso in recent years, as jihadist militants linked to Islamic State and al-Qaeda spread southwards.

The soldiers' statement cited "the ignorance and neglect of the situation of our brothers in arms who have fallen at the front and, above all, that of their families, abandoned to their sad fate by Mr Patrice Talon's policies".

The rebels also hit out at cuts in health care, including the cancellation of state-funded kidney dialysis, and taxes rises, as well as curbs on political activities.

Talon, who is regarded as a close ally of the West, is due to step down next year after completing his second term in office, with elections scheduled for April.

A businessman known as the "king of cotton", he first came to power in 2016. He has endorsed Finance Minister Romuald Wadagni as his successor.

Talon has been praised by his supporters for overseeing economic development, but his government has also been criticised for suppressing dissenting voices.

In October, Benin's electoral commission barred the main opposition candidate from contesting the election.

The attempted coup came just over a week after Guinea-Bissau's President Umaro Sissoco Embaló was overthrown - though some regional figures have questioned whether this was staged.

In recent years, West Africa has also seen coups in Burkina Faso, Guinea, Mali and Niger, prompting concerns about the region's stability.

Russia has strengthened its ties with these Sahel countries over recent years - and Burkina Faso, Mali and Niger have left the West African regional bloc Ecowas to form their own group, the Alliance of Sahel States.

News of the attempted takeover in Benin was hailed by several pro-Russian social media accounts, according to BBC Monitoring.

Iceland has joined Spain, Ireland, Slovenia and the Netherlands in saying it will boycott the 2026 Eurovision Song Contest.

All five countries have withdrawn after Israel's participation in the competition was officially confirmed last week.

"Participation of Israeli national broadcaster, KAN, in the contest has created disunity among both members of the European Broadcasting Union (EBU) and the general public," Icelandic broadcaster RÚV said in a statement.

Iceland had previously indicated it intended to skip the 2026 contest, but wanted to wait until the issue could be discussed by its board of directors on Wednesday.

A federal judge in New York has ruled the US Department of Justice can publicly release grand jury records from Jeffrey Epstein's 2019 sex trafficking case.

US District Judge Richard Berman's ruling reverses his previous decision to keep the material sealed. He cited a new law passed by Congress requiring the justice department to release files about Epstein by the end of next week.

Esptein was charged with sex trafficking in July 2019. He died in a New York prison cell a month later while awaiting trail.

The latest ruling comes a day after another judge made a similar ruling in the case of Ghislaine Maxwell, who was convicted in 2021 for her role in facilitating Epstein's abuse.

In his ruling, Judge Berman said the victims have the right to "have their identity and privacy protected", adding that their "safety and privacy are paramount".

The Epstein Files Transparency Act was signed into law by US President Donald Trump last month. It requires the justice department to release investigative material related to Epstein by 19 December, including unclassified records, documents and communications.

The law also allows the department to withhold files that involve active criminal investigations or raise privacy concerns.

A federal judge on Wednesday blocked President Donald Trump's deployment of National Guard troops in Los Angeles and ordered the troops be returned to the state governor's control.

In June, Trump sent thousands of National Guard troops to the California city in the wake of protests over his administration ramping up immigration raids in Los Angeles.

US District Judge Charles Breyer said the Trump administration had not proven that that the city's protests against immigration justified taking federal control of the state's National Guard.

The Trump administration still has control over 300 troops in Los Angeles six months after they were federalised, Judge Breyer said.

Breyer also denied the Trump administration's argument that the courts should not weigh in on a president taking control of state National Guard troops during an emergency.

"The Founders designed our government to be a system of checks and balances," Judge Breyer wrote in his ruling. "Defendants, however, make clear that the only check they want is a blank one."

Judge Breyer said his order would not go into effect until 15 December, giving the Trump administration time to make its expected appeal to a higher court.

The BBC has contacted the White House requesting comment.

This year, Trump has sent National Guard troops to several cities, including Portland, Oregon, and Washington DC, where the deployments have also been contested in courts and. in some cases, blocked by judges.

California Governor Gavin Newsom sued soon after Trump first deployed thousands of troops in June, but a court of appeals sided with the administration, saying the protests in Los Angeles justified Trump's federalisation of the National Guard.

Newsom filed a new legal challenge in November, arguing the protests in the city had largely subsided and therefore the troops were no longer necessary.

In a hearing in the case on Friday, lawyers for the Trump administration said the troops should stay in LA because federal immigration agents there were still being targeted.

But Judge Breyer seemed to question the need for troops to remain in the city months later.

"I think experience teaches us that crises come and crises go," he said, according to the Associated Press.

In his ruling, Judge Breyer said the Trump administration was "effectively creating a national police force made up of state troops" by sending California's National Guard troops to other states as well.

Judge Breyer previously ruled that the way Trump deployed the National Guard to Los Angeles this summer was illegal.

All 50 US states, the District of Columbia, and several territories have their own contingent of National Guard troops.

President Donald Trump's deployment of the National Guard to several US cities has drawn a round of legal challenges by state and local officials.

Trump has argued that his use of the troops is necessary to quell violence in Democratic-controlled cities, crack down on crime and support his deportation initiatives.

María Corina Machado, the winner of this year's Nobel Peace Prize, is "safe" and will come to Oslo, but will not be able to make the awards ceremony scheduled for 12:00 GMT on Wednesday, the Nobel Institute has said.

The Nobel Institute awarded the Venezuelan opposition leader the prize for "her struggle to achieve a just and peaceful transition from dictatorship to democracy" in her home country.

There has been much speculation about whether Machado, who has been living in hiding, would be able to defy a travel ban to attend the ceremony in Norway's capital.

Organisers said her daughter would accept the award in her stead.

In an audio recording shared by the Nobel Institute, Machado said "I will be in Oslo, I am on my way."

However, the director of the Nobel Institute, Kristian Berg Harpviken, said that Machado was expected to arrive "sometime between this evening and tomorrow morning" - too late for the ceremony.

In her mother's absence, Ana Corina Sosa is expected to give the speech Machado had prepared.

Earlier on Wednesday, the Nobel Institute had said they were in the dark about Machado's whereabouts, triggering concern among her supporters.

Two of her children and her mother are in Oslo, hoping to be reunited with Machado after being separated for more than a year.

Machado went into hiding shortly after Venezuela's disputed presidential election in July 2024.

The last time she was seen in public was on 9 January when she spoke to her supporters at a rally protesting against the swearing-in of Nicolás Maduro to a third term as president.

The elections were widely dismissed both by the opposition in Venezuela and on the international stage as rigged, and sparked protests across the country.

Around 2,000 people were arrested in the crackdown which followed, among them many members of Machado's opposition coalition.

Machado, who had managed to unite the bitterly divided opposition ahead of the election, went into hiding for fear of arrest.

She continued to give interviews and uploaded videos onto social media urging her followers not to give up.

The announcement that she had been chosen as this year's Nobel Peace Prize winner galvanised her supporters and triggered immediate speculation as to whether she would be able to travel to Oslo.

Total secrecy has surrounded her travel plans and it is not know how she managed to leave her place of hiding or by what means she has reached Europe.

Sporadic gunfire and explosions have been reported as M23 rebels advance towards a key city in eastern Democratic Republic of Congo, in an offensive that has forced thousands to flee across the border into Burundi.

Residents and military sources said soldiers were fleeing the assault on Uvira, the last government-held city in the mineral-rich region.

US President Donald Trump brokered a peace deal last week between DR Congo's President Félix Tshisekedi and Rwanda's Paul Kagame to end the long-running conflict.

Shops and schools have closed, with terrified residents staying indoors amid fears that rebels had taken control of some government buildings.

But South Kivu Governor Jean-Jacques Purusi dismissed reports that the rebels were in the city as "completely unfounded rumours".

Residents told local media that the rebels were patrolling central Uvira under the cover of darkness on Tuesday night, while the city remained deserted early on Wednesday.

A local rights official told AP news agency that there was a "risk of a massacre" if the remaining soldiers mounted strong resistance.

"It's chaotic, nobody's in charge. Uvira is done for," a Burundian officer told AFP news agency.

"Three bombs have just exploded in the hills. It's every man for himself," a resident told AFP, while another added: "We are all under the beds in Uvira - that's the reality."

Military and security sources said the rebel fighters advanced from the north, near the Burundian border.

In an interview with UN-backed Radio Okapi, Purusi denied Uvira had fallen to the M23, saying the city remained under the control of government forces.

The US, European Union, and eight European nations have accused Rwanda of supporting the rebel offensive, and have called for an immediate halt to the fighting

In a joint statement, they voiced "profound concern" about the violence, and said it had a "destabilising potential for the whole region".

Rwanda has denied any involvement in the fighting, accusing DR Congo's government and its ally, Burundi, of violating a ceasefire.

UN experts say Rwanda's army is in "de facto control of M23 operations".

About 200,000 people have fled their homes in eastern DR Congo since the latest round of fighting started early this month, the UN says.

It said at least 74 people had been killed, mostly civilians, and 83 admitted to hospital with wounds.

A Burundian administrative source told AFP that he had recorded more than 8,000 daily arrivals over the past two days, and 30,000 arrivals in one week.

The latest offensive comes nearly a year after the M23 rebels seized control of Goma and Bukavu, the other two main cities in eastern DR Congo.

The M23 is not part of the US-brokered peace deal, and is in separate talks with DR Congo's government in mediation efforts led by Qatar.

In a national address on Monday, Tshisekedi accused Rwanda of "deliberate violations" of the peace accord.

"This is a proxy war aimed at challenging our sovereignty over a highly strategic area, rich in critical minerals and economic potential that is crucial to the future of our nation," Tshisekedi said.

For its part, Rwanda accused the armies of DR Congo and Burundi of bombing villages near its border, forcing more than 1,000 civilians to flee into its territory.

Eastern DR Congo has been wracked by conflict for more than 30 years, since the 1994 Rwandan genocide. Several peace deals going back to the 1990s have collapsed.

Numerous armed groups have competed with the central authorities for power and control of the potential fortune in this vast nation.

Two US fighter jets were tracked circling the Gulf of Venezuela on Tuesday as tensions continue to escalate between the two countries.

The F/A-18 Super Hornets appeared on flight tracking sites near Maracaibo, Venezuela's second-largest city, at around 13:00 (17:00 GMT), before circling the gulf for about 40 minutes.

A US defence official told the Associated Press the F/A-18 jets had conducted a "routine training flight" in the area.

The incident comes amid a wave of US strikes against boats in the Caribbean Sea, which the White House said were trafficking drugs to the US from Venezuela. Experts have raised questions over the legality of the strikes, which have killed more than 80 people.

Venezuelan President Nicolás Maduro has accused the US of using the strikes to destabilise the country and oust him from power.

In an interview conducted with Politico the day before the jets approached Venezuela's coastline, Trump declared that Maduro's days in power were "numbered", and declined to comment on whether US troops could be deployed to the country.

A separate jet, an EA-18G Growler, also appeared just before the F/A-18s on the tracking site FlightRadar24. Data shows the jet flew loops just north of Venezuela's coast.

They are the latest in a number of unusual US air force activities that have been tracked since September. B-52 Stratofortress and B-1 Lancer bombers previously flew up to and along the Venezuelan coast.

But the F/A-18s, which are capable of engaging targets both on the ground and in the air, appear to be the first to approach the Venezuelan coastline so publicly in recent months. The F/A-18s came within 20 nautical miles of the coastline, flight tracking data showed.

Neither the F/A-18s or the Growler showed a point of origin or a destination on FlightRadar24, and all three aircraft only turned on their transponders when they arrived near the Venezuelan coastline. Justin Crump, head of the risk consultancy Sibylline, suggested the move was intended to "support the administration's signalling and put pressure on the [Venezuelan] leadership".

The F/A-18s - which operated under the callsigns RHINO11 and RHINO12 - flew six loops up and down the Gulf of Venezuela. Meanwhile, the Growler jet - flying under the codename GRIZZLY2 - also flew circles along the coast.

Greg Bagwell, a former RAF air marshall and president of the Air and Space Power Association, told BBC Verify that the flights appeared to be "probing" Venezuelan defence and trying to check for responses such as radio traffic and encrypted signals related to defence systems.

"The Growlers would have been listening for [signals intelligence], whilst the Super Hornets would have been providing air defence cover for the Growlers," Baswell said. He said the Growlers would also detect "active missile sites".

"It could be construed as the early gathering of intelligence for subsequent operations, or just a warning of such," he added.

Crump said the jets also had the capacity to test out "jamming capabilities", adding: "This also helps send a message, when successful, potentially indicating to Venezuela's leadership that these systems cannot or should not be relied upon," he said.

The US has deployed troops, ships and jets to the Caribbean in recent months, which officials have said is to combat drug trafficking in the area.

On Tuesday the US Southern Command published photos of an F/A-18 operating from the USS Gerald Ford, the world's largest aircraft carrier, which has been sent to the Caribbean.

Analysis of satellite images and ship tracking websites by BBC Verify has made it possible to identify at least nine military vessels that have been deployed to the region over recent weeks.

Satellite images also show that an airbase in Puerto Rico, which was closed in 2004 by the Pentagon, has been re-activated. Repairs have been carried out to the runway at Roosevelt Roads base and F-35s - America's most advanced fighter - have been sent to the base.

What do you want BBC Verify to investigate?

Four Afghan men were ordered to report to the Taliban government's department of vice and virtue for dressing in costumes inspired by the TV series Peaky Blinders.

The friends were told that their clothing was "in conflict with Afghan and Islamic values", a Taliban spokesman told the BBC, adding the values in Peaky Blinders went against Afghan culture.

In videos posted online, the men, who have been released, can be seen posing in flat caps and three-piece suits similar to those worn in the series set in England soon after World War One.

Since the Taliban seized power in 2021, they have imposed a number of restrictions on daily life in accordance with their interpretation of Islamic Sharia law.

"Even jeans would have been acceptable, but the values in the Peaky Blinders series are against Afghan culture," Saiful Islam Khyber, a spokesman for the Taliban government's provincial department of Vice and Virtue in Herat city told the BBC.

The men, all in their early twenties, come from the town of Jibrail in Herat province. They were ordered to report to the Taliban's "morality police" on Sunday, and presented themselves for questioning in Herat the following day.

"They were promoting foreign culture and imitating film actors in Herat," Khyber wrote on social media, adding that they had undergone a "rehabilitation programme".

The were not formally arrested, "only summoned and advised and released", Khyber told the BBC's US partner CBS News.

"We have our own religious and cultural values, and especially for clothing we have specific traditional styles," he said.

"The clothing they wore has no Afghan identity at all and does not match our culture. Secondly, their actions were an imitation of actors from a British movie. Our society is Muslim; if we are to follow or imitate someone, we should follow our righteous religious predecessors in good and lawful matters."

The men could be seen thanking officials for their advice and saying they were unaware they had violated any laws in a video released by the ministry after they were questioned - though it is unclear under what circumstances the interview was recorded.

"I have innocently been sharing content that was against Sharia which had many viewers," one said in the recording.

He said he had been "summoned and advised", and would no longer do "anything like this".

In an interview with YouTube channel Herat-Mic uploaded at the end of November, before they were summoned, the friends said they admired the fashion displayed in the series, adding that they had received positive reactions from locals.

"At first we were hesitant, but once we went outside, people liked our style, stopped us in the streets, and wanted to take photos with us," one of the men said, according to a translation by CBS News.

The US has imposed sanctions on a network it says is recruiting former Colombian soldiers and training individuals to fight in Sudan's civil war.

Eight entities and individuals - primarily of Colombian nationality - have been aiding the Sudanese paramilitary Rapid Support Forces (RSF), the US Treasury's Office of Foreign Assets Control (OFAC) said on Tuesday.

Its statement added that hundreds of Colombian mercenaries have travelled to Sudan since 2024, including to serve as infantry and drone pilots for the RSF.

Last year, Colombian President Gustavo Petro said those who "spill young blood for money in foreign countries must be punished criminally".

The participation of soldiers - both former and active - in foreign conflicts dates back decades to the US wars in Afghanistan and Iraq, in exchange for American military aid in Colombia's war on drugs and armed groups.

"This created an even greater number of Colombian soldiers who, two decades later, are beginning to retire without a sufficient source of income," a retired military officer turned academic told BBC Mundo.

Alfonso Manzur explained that as a result, "we see more Colombian ex-soldiers on missions abroad".

Retired Colombian soldiers are commonly recruited under false promises of low-risk work, before appearing on the frontlines, such as in the current conflict between Russia and Ukraine, and in Sudan.

In 2024, the Colombian foreign ministry said it was aware of citizens being deceived by what it called "sophisticated human trafficking networks", and becoming mercenaries in international conflicts.

On Tuesday, the US Treasury's OFAC said it was targeting a network for recruiting fighters for the RSF, which has been battling the Sudanese army since April 2023.

"The RSF has shown again and again that it is willing to target civilians - including infants and young children," said John Hurley, the Treasury's under-secretary for terrorism and financial intelligence.

"Its brutality has deepened the conflict and destabilized the region, creating the conditions for terrorist groups to grow."

The State Department has said the group and its allied militias have attacked civilians, systematically killed men and boys and deliberately targeted and raped women and girls.

Earlier this year, it determined that RSF members had committed genocide, although both the paramilitary group and the army have repeatedly been accused of war crimes.

The transnational network accused of aiding the group consists of four entities and four individuals, including a dual Colombian-Italian national who is a former military officer, now based in the United Arab Emirates, a country repeatedly accused of arming the RSF. It denies the allegations.

"All property and interests in property of the designated or blocked persons... or in the possession or control of U.S. persons are blocked and must be reported", the Treasury said.

The US has accused the primarily Colombian network of recruiting mercenaries to serve with the RSF, providing "tactical and technical expertise", and even training children to fight.

According to its statement, Colombian fighters were involved in "numerous battles across Sudan" including in the capital Khartoum, Omdurman, Kordofan, and el-Fasher.

On the ground, the RSF has been making gains, most notably seizing the city of el-Fasher in October, after a 500-day starvation siege.

It is estimated that more than 5,000 people were killed as the paramilitary rampaged through the army's last stronghold in Darfur.

The three states that make up Kordofan, home to almost eight million people, and situated between Khartoum and Darfur, has recently become a major frontline.

On Monday, at least 114 people, including 63 children, were killed in strikes on a kindergarten and hospital in South Kordofan, the World Health Organisation said.

WHO director-general Tedros Adhanom Ghebreyesus described the attack as "senseless" as he repeated calls for a ceasefire.

The RSF also claimed control of Sudan's largest oil field, Heglig, in what the paramilitary group hailed as "a turning point for the liberation" of the country.

Last month, US President Donald Trump pledged to "start working on Sudan" with Egypt, Saudi Arabia and the UAE, posting on social media that "tremendous atrocities" were taking place.

Nearly 12 million people have been driven from their homes with famine conditions in parts of the country.

A daughter of South Africa's former President Jacob Zuma has been sworn into parliament, less than a fortnight after her half-sister was forced to step down.

Brumelda Zuma became one of South Africa's newest MPs on Wednesday, representing uMkhonto weSizwe (MK), the opposition party led by her father.

Her half-sister, Duduzile Zuma-Sambudla, resigned from parliament following allegations that she had tricked 17 men into fighting for Russia as mercenaries in Ukraine. Zuma-Sambudla has denied these accusations.

Brumelda Zuma's appointment suggests the former president intends to ensure his family is represented in parliament.

She was sworn in alongside three other MK members, who, the party said, "bring a wealth of experience and dedication" to parliament.

She said she would focus mostly on ensuring that South Africans had "good public services" because "that is what I studied".

MK said Brumelda Zuma had a degree in public administration.

Brumelda Zuma has not previously had a national profile, unlike her half-sister who had represented South Africa in the Pan-African Parliament.

MK previously said it was Zuma-Sambudla's decision to resign as she wanted to focus her efforts on ensuring the return of those trapped in Ukraine's war-torn Donbas region.

She was implicated in the Russia recruitment scheme after South Africa's government revealed it had received distress calls from more than a dozen citizens who had joined mercenary forces.

The men are aged between 20 and 39 and are trapped in Donbas.

One of Zuma-Sambudla's most prominent accusers is another half-sister, Nkosazana Zuma-Mncube.

Zuma-Mncube filed a criminal complaint against Zuma-Sambudla and two other people, accusing them of luring the men to Russia "under false pretences" and then handing them to a Russian mercenary group "without their knowledge or consent".

She said that eight of them were her relatives.

Police have confirmed they are carrying out an investigation.

Working as a mercenary or fighting for another army is illegal under South African law, unless the government authorises it.

Zuma-Sambudla has said in an affidavit that she thought the men were going to Russia for "lawful" training.

She is currently also on trial on terrorism-related charges over social media messages she posted during deadly protests in 2021. She has denied the charges.

Jacob Zuma formed MK in 2023 after a massive fall-out with current President Cyril Ramaphosa.

The MK party came in third place in South Africa's general election last year, and became the main opposition party in parliament after the second-biggest party joined a coalition government led by Ramaphosa.

South Korea has lodged a complaint with the Chinese and Russian defence attaches based in the country, a day after their warplanes entered its air defence zone.

Seoul said it sent up fighter jets to "take tactical measures in preparation for any emergencies" after seven Russian and two Chinese military aircraft "briefly entered" the zone on Tuesday, but noted they "did not violate" South Korea's airspace.

Some countries delineate air identification defence zones, wherein they require foreign planes to identify themselves. These are not part of sovereign airspaces under international law.

In March this year, Seoul also deployed fighter jets after several Russian warplanes flew into the zone.

The Russian aircraft entered Korea's Air Defense Identification Zone (Kadiz) near Ulleung Island and Dokdo, while the Chinese aircraft entered near Ieodo, a Joint Chiefs of Staff official said, according to South Korean media.

Both sides' aircraft then regrouped in the airspace near Japan's Tsushima Island, the official said.

"Our military will actively respond to aircraft activities from neighbouring countries in the Kadiz in compliance with international law," South Korea's defence ministry said on Wednesday when lodging the complaint.

Both Japan and South Korea have laid claims to the Dokdo island grouping, as has North Korea.

Ieodo - a submerged rock above the South Korean island of Jeju - is a point of dispute between Seoul and Beijing, each of whom have included it in their air defence zones.

China on Wednesday confirmed that its air force had conducted a joint patrol with Russia in the East China Sea and Western Pacific airspace.

The exercise was part of an "annual cooperation plan" between Beijing and Moscow to "address regional challenges and maintain regional peace and stability", said a national defence spokesman.

China and Russia have entered South Korea's air defence zone without notification on several occasions since 2019, often during similar exercises.

Russia does not recognise South Korea's air defence zone, describing it as "unilaterally" established and saying it should therefore not create any legal obligations for other countries.

Tourists from dozens of countries including the UK could be asked to provide a five-year social media history as a condition of entry to the United States, under a new proposal unveiled by American officials.

The new condition would affect people from dozens of countries who are eligible to visit the US for 90 days without a visa, as long as they have filled out an Electronic System for Travel Authorization (ESTA) form.

Since returning to the White House in January, President Donald Trump has moved to toughen US borders more generally - citing national security as a key reason.

Analysts say the new plan could pose an obstacle to potential visitors, or harm their digital rights.

The US expects a major influx of foreign tourists next year, as it hosts the men's football World Cup alongside Canada and Mexico, and for the 2028 Olympics in Los Angeles.

The proposal document was filed by Customs and Border Protection (CBP) and the Department of Homeland Security (DHS), of which the agency is part.

US media reported that it appeared in the Federal Register, which is the official journal of the US government. The BBC has asked DHS for comment.

It says "the data element will require ESTA applicants to provide their social media from the last 5 years", without giving further details of which specific information will be required.

The existing ESTA requires a comparatively limited amount of information from travellers, as well as a one-off payment of $40 (£30). It is accessible to citizens of about 40 countries - including the UK, Ireland, France, Australia and Japan - and allows them to visit the US multiple times during a two-year period.

As well as the collection of social media information, the new document proposes the gathering of an applicant's telephone numbers and email addresses used over the last five and 10 years respectively, and more information about their family members.

The text cites an executive order from Trump in January, titled "Protecting the United States From Foreign Terrorists and Other National Security and Public Safety Threats".

The Trump administration has previously required foreign nationals to make their social media accounts public if they are applying for student visas or H1B visas for skilled workers - the latter of which now also entail a much higher fee.

A senior state department official said of the student visa policy: "It is an expectation from American citizens that their government will make every effort to make our country safer, and that is exactly what the Trump Administration is doing every single day."

Officers were instructed to screen for those "who advocate for, aid, or support designated foreign terrorists and other threats to national security; or who perpetrate unlawful anti-Semitic harassment or violence".

As part of the administration's broader effort to toughen borders, officials recently said an existing travel ban - affecting 19 countries in Africa, the Middle East and the Caribbean - could soon be expanded.

That move was announced in the wake of a shooting attack on two National Guard members in Washington DC, in which an Afghan man has been named as the suspect.

The new proposal regarding ESTA data collection for tourists invites views from the public for 60 days.

Sophia Cope, of digital rights organisation the Electronic Frontier Foundation, criticised the plan, telling the New York Times that it could "exacerbate civil liberties harms".

Meanwhile, immigration law practice Fragomen suggested there could be practical impacts as applicants could face longer waits for ESTA approvals.

Experts have previously suggested that the changes to travel policies introduced under Trump have had an impact on the American tourism industry.

Earlier this year, the World Travel & Tourism Council said the US was the only one of 184 economies that it analysed that was expected to see a decline in international visitor spending in 2025.

Other Trump administration policies have also appeared to impact tourism to the country, such as many Canadians boycotting US travel as a form of protest against Trump's tariffs.

October marked the 10th straight month of decline in the number of Canadian travellers to the US. In the past, Canadians have made up about a quarter of all international visitors to the US, spending more than $20bn (£15.1bn) a year, according to the US Travel Association.

María Corina Machado, the winner of this year's Nobel Peace Prize, is "safe" and will come to Oslo, but will not be able to make the awards ceremony scheduled for 12:00 GMT on Wednesday, the Nobel Institute has said.

The Nobel Institute awarded the Venezuelan opposition leader the prize for "her struggle to achieve a just and peaceful transition from dictatorship to democracy" in her home country.

There has been much speculation about whether Machado, who has been living in hiding, would be able to defy a travel ban to attend the ceremony in Norway's capital.

Organisers said her daughter would accept the award in her stead.

In an audio recording shared by the Nobel Institute, Machado said "I will be in Oslo, I am on my way."

However, the director of the Nobel Institute, Kristian Berg Harpviken, said that Machado was expected to arrive "sometime between this evening and tomorrow morning" - too late for the ceremony.

In her mother's absence, Ana Corina Sosa is expected to give the speech Machado had prepared.

Earlier on Wednesday, the Nobel Institute had said they were in the dark about Machado's whereabouts, triggering concern among her supporters.

Two of her children and her mother are in Oslo, hoping to be reunited with Machado after being separated for more than a year.

Machado went into hiding shortly after Venezuela's disputed presidential election in July 2024.

The last time she was seen in public was on 9 January when she spoke to her supporters at a rally protesting against the swearing-in of Nicolás Maduro to a third term as president.

The elections were widely dismissed both by the opposition in Venezuela and on the international stage as rigged, and sparked protests across the country.

Around 2,000 people were arrested in the crackdown which followed, among them many members of Machado's opposition coalition.

Machado, who had managed to unite the bitterly divided opposition ahead of the election, went into hiding for fear of arrest.

She continued to give interviews and uploaded videos onto social media urging her followers not to give up.

The announcement that she had been chosen as this year's Nobel Peace Prize winner galvanised her supporters and triggered immediate speculation as to whether she would be able to travel to Oslo.

Total secrecy has surrounded her travel plans and it is not know how she managed to leave her place of hiding or by what means she has reached Europe.

At least 19 people have been killed and a further 16 injured after two buildings collapsed in the Moroccan city of Fez.

The two four-storey residential buildings that came down early on Wednesday morning contained eight families, state media report, citing local officials.

Several Moroccan news outlets report that the buildings - located in the south-westerly Al Massira suburb of the new part of the city - had shown signs of deterioration for several years.

Fez, in north-eastern Morocco, is one of the North African nation's oldest cities, with parts dating back to the 8th Century, as well as being its third-most populous.

A search and rescue operation is ongoing to find anyone who may still be trapped under the rubble. Footage from the scene shows people and diggers sifting through the debris under the cover of darkness.

In one clip, published by news site Akhbarona, a body can be seen being carried away on a stretcher by emergency services.

Residents of nearby buildings have been evacuated as a preventative measure, state media report.

Those taken to hospital suffered varying injuries.

Nine were killed when a condemned building collapsed in a different neighbourhood of Fez in May.

Prior to that, five people were killed when a house in the old city crumbled in February 2024, following heavy rain and strong winds.

Elon Musk says he would not lead the Department of Government Efficiency (Doge) if he had his time again, but has maintained that its tumultuous efforts to shrink the size of the US government under President Donald Trump was "a little bit successful".

The billionaire boss of Tesla and SpaceX gave his reflections during a nearly-hour long interview on The Katie Miller Podcast on Tuesday.

Musk left Doge in May after initially promising to save as much as $2tn (£1.5bn) a year by slashing federal jobs and shuttering government programmes, among other cost-cutting measures.

Doge's website, which was last updated on 4 October, claims to have saved an estimated $214bn so far this year.

Conservative podcast host Miller, a former White House adviser herself who worked as a spokesperson for Doge, asked Musk whether he would do his work for the organisation again if he could rewind to the start of the year.

"I mean no, I don't think so," Musk replied.

Instead, he said he would have "worked in my companies, essentially", explaining that "they wouldn't have been burning the cars".

His comments reference a series of vandalism attacks on Tesla showrooms and vehicles earlier this year, which came in response to the highly visible political role in the Trump administration for the world's richest man.

Musk's involvement in US politics sparked global protests and boycotts against Tesla, and led to a spike in vandalism of Tesla's Cybertruck vehicles. In April, the firm said sales had fallen to their lowest level in three years and warned investors that "changing political sentiment" could continue to hurt demand.

But Musk said he believed Doge had been "a little bit successful, we were somewhat successful".

"You really want the least amount done by government as possible," he explained, adding that Doge had "stopped a lot of funding that really just made no sense".

Musk told Miller that Doge, which was created by an executive order on Trump's first day back in the White House, was a "made-up" name "based on internet suggestions".

The advisory group, which is not an official government department, tackled Musk's vision at a fierce pace. It pushed for massive reductions in the federal workforce, as well as the shuttering of programmes and even agencies such as the US Agency for International Development (USAID).

Some of Doge's moves were met with legal fights, or were reversed. When the group's cost-cutting resulted in bird flu officials at the US Department of Agriculture being fired, the Trump administration looked to re-hire them days later.

Musk's time at the helm of Doge not only appeared to cause issues for his business empire - it also led to an explosive falling-out with the president himself.

Musk donated millions of dollars to the Trump campaign during the election and was a fixture at the White House for months, speaking at cabinet meetings and standing behind the president at events in the Oval Office.

But that relationship came to a grinding halt in June when Musk broke with the White House narrative and criticised a Trump-backed spending bill.

It led to a war of words on social media, with Trump at one point threatening to order Doge to look into Musk's own business dealings with the US government.

The pair's relationship now seems to be mended. Musk was spotted at a White House dinner with Saudi Crown Prince Mohammad bin Salman in November.

And Musk spoke positively of Trump in his interview with Miller, saying the president was the funniest person he knows and has "great sense of humour".

Australia's world-first social media ban for children has taken effect, with throngs of teenagers waking up to find their accounts have gone dark.

Others tell BBC they have already snuck past barriers and will continue scrolling and posting freely until they are caught.

The new law means social media firms - including Meta, TikTok and YouTube - must take "reasonable steps" to ensure Australians aged under 16 don't hold accounts on their platforms.

The ban, eyed with excitement by global leaders and trepidation by tech companies, was justified as necessary to protect children from harmful content and algorithms - though critics have argued blanket prohibition is neither practical nor wise.

This landmark policy has been one of Prime Minister Anthony Albanese's pet projects, and speaking to media on Wednesday he said he believed it has the power to change lives around the world.

"This is a day in which my pride to be prime minister of Australia has never been greater," he said, flanked by parents and media figures who had pushed for the ban.

"This is Australia showing enough is enough."

"I think it will go [down] with the other great reforms that Australia has led the world on."

Various governments, from the US state of Florida to the European Union, have been experimenting with limiting children's use of social media. But, along with a higher age limit of 16, Australia is the first jurisdiction to deny an exemption for parental approval in a policy like this - making its laws the world's strictest.

Countries like Denmark, Malaysia, Singapore, Greece and Brazil are among those who have said they're looking at Australia as a test case.

The Australian government has named 10 social media platforms as a start, including all of the most popular ones, but has also warned others it's coming for them next.

Online safety regulator, Julie Inman Grant, said her agency will start checking compliance from Thursday. Parents and children won't be liable under this law, only social media firms, which face fines of up to A$49.5m ($33m, £24.5m) for serious breaches.

"Tomorrow, I will issue information notices to the 10 major platforms and we will provide information to the public before Christmas on how these age restrictions are being implemented and whether, preliminarily, we see them working," she said.

There is broad agreement in Australia that social media companies are failing to shield users, particularly children, from harm on their platforms.

Tasmanian student Florence Brodribb - known as Flossie - told the press she believed the ban would help kids like her grow up "healthier, safer, kinder, and more connected".

"Our brains are going through one of the biggest rewiring periods of our lives... Social media is designed to take advantage of that," the 12-year-old said.

"Young people deserve better than that."

Polling shows the ban is wildly popular with parents, who hope it will also help reduce cyber bullying and child exploitation. But it is far less popular with children.

Backed by some mental health advocates, many have argued it robs young people of connection - particularly those from LGBTQ+, neurodivergent or rural communities - and will leave them less equipped to tackle the realities of life on the web.

"My closest friend would be 30km (18.6 miles) away from me... and my next closest friend is probably over 100km," 15-year-old Breanna told the BBC.

"When our Snapchat is taken away, so is our communication."

Experts are also worried kids are going to circumvent the ban with relative ease - either by tricking the technology that's performing the age checks, or by finding other, potentially less safe, places on the net to gather.

Many critics have been advocating instead for better education and more moderation, with Sydney father-of-two Ian among them.

"There's a good idea behind [the policy], but is it the right way to go about it? I'm not sure," he told the BBC.

Tech firms, which are desperate to stop other countries from implementing similar bans, have argued the government is overreaching, and pointed to recently strengthened parental controls on many of their platforms as a solution.

While the government has insisted the social media companies have the money and the technology to make this ban happen, it has also sought to manage expectations.

"I've been asked... what will success look like? Success is the fact that it's happening. Success is the fact that we're having this discussion," Albanese said on Wednesday.

"We do acknowledge it won't be perfect and we'll work through it."

Ms Inman Grant said Australia is playing the long game, and while stories of kids getting round the ban will make headlines, regulators will not be deterred.

"The world will follow, like nations once followed our lead on plane tobacco packaging, gun reform, water, and sun safety," she said.

The leader of France's far-right National Rally (RN) Jordan Bardella has welcomed "for the most part" concerns raised about Europe in US President Donald Trump's new National Security Strategy.

Last week, the White House published a document which outlined Trump's vision of the world and the state of the European continent, which many have characterised as harshly critical of Europe.

Speaking to the BBC's Nick Robinson for his Political Thinking podcast, Bardella praised what he said was Trump's "appeal to American pride" - but he made clear he did not want Europe to be "subservient to any major power".

He said there was a "wind of freedom, of national pride blowing all over Western democracies".

In a wide-ranging interview, the 30-year-old, who opinion polls suggest leads in the race to be France's next president, was also challenged on the RN's political history and his stance on immigration.

Bardella said he shared the majority of the concerns outlined by the Trump administration about Europe facing "civilisational erasure", which the White House said is being fuelled by a range of policies, including on migration.

"Mass immigration and the laxity of our governments in the last 30 years with regards to migration policy are shaking the balance of European countries, of Western societies, and namely French society," Bardella said.

Snap parliamentary elections in June 2024 made the RN the largest single force in parliament, although an alliance of left-wing parties clinched victory.

The next French presidential election is due to be held in 2027. A recent poll for Le Figaro suggests Bardella would win with 44% of the vote - just ahead of Marine Le Pen, the RN figurehead whose candidacy is in doubt after she was found guilty of embezzling EU funds and barred from standing in an election for five years.

An appeal due early next year will determine whether Le Pen can run - otherwise, the expectation is that Bardella will step in.

Bardella batted away suggestions this was sparking tensions between them, stating they were united by "trust and friendship".

"I will fight by her side so she can win the appeal. Until the appeal we will campaign together, as we will after, hand-in-hand," he said in his interview.

The RN was founded by Le Pen's father Jean-Marie in 1972. Known then as the National Front (FN), it has since become a decisive force in French politics. Jean-Marie Le Pen was convicted several times for Holocaust denial and was an unrepentant extremist on race.

In his interview with Nick Robinson, Bardella distanced himself from Jean-Marie Le Pen's comments, as have many other RN politicians in recent years.

"I am fighting against the caricature of my political movement, of my ideas," he said, adding his responsibility was to bring together the French people and present the country with "a project of national recovery".

"My people's expectations for a break with the past are numerous," Bardella added.

Challenged on the racist and antisemitic history of the RN's precursor, Bardella rejected accusations that the National Front had ever put forward arguments that could "offend" some sections of the population

"A lot of Jewish people vote for us and consider us a bulwark against extremism," he said.

The RN is primarily known as an anti-immigration party and has long pushed for France to have stricter immigration rules, including limiting social spending to French citizens.

"If tomorrow I am the head of government, France will no longer be the target of mass immigration," he said, adding that if elected his first provision would be to trigger a referendum on immigration. "It will allow us to take back control of our borders."

However, according to the French constitution, a referendum can only be held on certain subjects which do not include immigration, so the constitution would have to be amended first. In order to do so, the RN would have to clinch the presidency and have either an absolute majority in Parliament or enough allies.

Bardella - who grew up in the Paris region but himself has parents of immigrant origin - drew a clear distinction between people who he said were born in France but "reject republican institutions like the police or values like secularism", and others who "do everything to become French - espouse the language, culture and national patrimony".

When pressed on what it means to be French if being born in the country is not sufficient, Bardella said he felt being French was an "honour" that transcended bureaucracy.

"Being French is adhering to some values and lifestyles, believing in equality between men and women," he argued.

"I defend secularism and I feel that Islamism has today become a separate political project... which wants to impose its rules on French society," Bardella added, before promising to close down radical mosques and banning "hate preachers" from the country if elected.

Although he did not expand on France's frequent and longstanding financial woes - the country's debt is more than €3 trillion, or around 114% of Gross Domestic Product (GDP) - Bardella said the French economy was "sick".

"We face two ailments – excessive taxation and excessive regulation," he said, promising to free the country from the "shackles" that limit growth. The RN has repeatedly voted down the yearly budgets put forward by governments since last year, and has promised to similarly vote down this year's.

Bardella's position on Ukraine also bears some differences with that of the current centrist government. While he stated Russia represented a "multidimensional threat to French and European interests", and that Kyiv will need security guarantees even in the event of a peace deal, he also said that he was "firmly opposed" to sending soldiers to Ukraine.

Emmanuel Macron's government, on the other hand, has proposed deploying a steady military presence, albeit far from the front line.

But such a decision "would contribute to an escalation," Bardella said, "especially given that we have nuclear weapons and that President Putin has intentions whose limits are unclear".

If Bardella does stand at the next presidential election and wins, he will be 31.

Macron was 39 when he became France's youngest ever president in 2017. While Macron was finance minister for two years under François Hollande, Bardella, in comparison, has never been in government.

"It's true I am 30 years old. Unfortunately I can't do anything about that," he argued.

"I recognise the existential questions facing our country... And I'd rather be told that today is 'too soon' rather than tomorrow is 'too late'."

Sporadic gunfire and explosions have been reported as M23 rebels advance towards a key city in eastern Democratic Republic of Congo, in an offensive that has forced thousands to flee across the border into Burundi.

Residents and military sources said soldiers were fleeing the assault on Uvira, the last government-held city in the mineral-rich region.

US President Donald Trump brokered a peace deal last week between DR Congo's President Félix Tshisekedi and Rwanda's Paul Kagame to end the long-running conflict.

Shops and schools have closed, with terrified residents staying indoors amid fears that rebels had taken control of some government buildings.

But South Kivu Governor Jean-Jacques Purusi dismissed reports that the rebels were in the city as "completely unfounded rumours".

Residents told local media that the rebels were patrolling central Uvira under the cover of darkness on Tuesday night, while the city remained deserted early on Wednesday.

A local rights official told AP news agency that there was a "risk of a massacre" if the remaining soldiers mounted strong resistance.

"It's chaotic, nobody's in charge. Uvira is done for," a Burundian officer told AFP news agency.

"Three bombs have just exploded in the hills. It's every man for himself," a resident told AFP, while another added: "We are all under the beds in Uvira - that's the reality."

Military and security sources said the rebel fighters advanced from the north, near the Burundian border.

In an interview with UN-backed Radio Okapi, Purusi denied Uvira had fallen to the M23, saying the city remained under the control of government forces.

The US, European Union, and eight European nations have accused Rwanda of supporting the rebel offensive, and have called for an immediate halt to the fighting

In a joint statement, they voiced "profound concern" about the violence, and said it had a "destabilising potential for the whole region".

Rwanda has denied any involvement in the fighting, accusing DR Congo's government and its ally, Burundi, of violating a ceasefire.

UN experts say Rwanda's army is in "de facto control of M23 operations".

About 200,000 people have fled their homes in eastern DR Congo since the latest round of fighting started early this month, the UN says.

It said at least 74 people had been killed, mostly civilians, and 83 admitted to hospital with wounds.

A Burundian administrative source told AFP that he had recorded more than 8,000 daily arrivals over the past two days, and 30,000 arrivals in one week.

The latest offensive comes nearly a year after the M23 rebels seized control of Goma and Bukavu, the other two main cities in eastern DR Congo.

The M23 is not part of the US-brokered peace deal, and is in separate talks with DR Congo's government in mediation efforts led by Qatar.

In a national address on Monday, Tshisekedi accused Rwanda of "deliberate violations" of the peace accord.

"This is a proxy war aimed at challenging our sovereignty over a highly strategic area, rich in critical minerals and economic potential that is crucial to the future of our nation," Tshisekedi said.

For its part, Rwanda accused the armies of DR Congo and Burundi of bombing villages near its border, forcing more than 1,000 civilians to flee into its territory.

Eastern DR Congo has been wracked by conflict for more than 30 years, since the 1994 Rwandan genocide. Several peace deals going back to the 1990s have collapsed.

Numerous armed groups have competed with the central authorities for power and control of the potential fortune in this vast nation.

President Donald Trump has told a campaign-style rally that consumer prices are falling "tremendously" as he sought to allay voter anxiety about the US cost of living.

In a speech at a casino in the battleground state of Pennsylvania, the president told supporters he had "no higher priority than making America affordable again".

But while gas and egg prices have fallen, other food is more expensive and Americans remain unhappy about the cost of housing, childcare and healthcare.

Democrats have capitalised on Trump's political vulnerability on the economy in recent off-cycle votes, leaving many Republicans uneasy about next year's midterms elections.

Tuesday's event in a swing district of Pennsylvania was the first of what the White House says will be a series of campaign-like rallies aimed at bringing its economic message to voters.

But at one point in his remarks, the Republican president again portrayed concerns about affordability as a Democratic "hoax".

In recent weeks, his administration has removed tariffs from dozens of food products and touted its rollback of fuel efficiency standards and Trump-branded retirement accounts for children as cost-of-living fixes.

In an excerpt from an interview with Politico released on Tuesday, Trump was asked what grade he would give the economy.

"A plus-plus-plus-plus-plus," he said.

In a sign the policy pivot might be cutting through, Trump's approval rating rose three points to 41% in a new Reuters/Ipsos poll.

But many Americans remain downbeat on the economy.

Alaina Hunt, 37, who lost her job as a designer at a construction company in Oklahoma City, told the BBC her position was in part a casualty of Trump's tariffs on steel and aluminium.

The construction sector "really took a hard hit very early on", she said. Ms Hunt says she has applied for at least 75 jobs in web design and development since April, to no avail, amid a broader slowdown in hiring.

She says rising grocery bills - about $25 extra per week - have added to the strain.

"I was able to scrape by a lot easier in years before," said Ms Hunt, who voted for Kamala Harris. "I don't think that the federal government is listening at all."

Economic data paints a mixed picture.

US consumer confidence fell in November to its lowest level since the spring.

But the stock market continues to hover near record highs. And forecasters expect the economy to expand by 1.9% this year, slower than last year's 2.8% but still better than expected.

Some recent data also indicate the job market may be picking up, after a significant hiring slowdown earlier this year.

As of September, inflation stood at 3%, the same rate as in January when the president took office and stubbornly above the Federal Reserve's 2% target.

It is still way below a peak of 9.1% under former President Joe Biden when the US faced its worst inflation in four decades.

Overall prices have surged 25% over the last five years, generating widespread frustration, despite wage growth over that period.

Beth Richardson, a 45-year-old from Kansas, said she had been floored by some of the prices at the grocery store near her, recalling a pack of Mentos gum she picked up recently that rang up to almost $5 with tax.

"I'm like, I'm just going to go die now because this cannot be," she said.

Ms Richardson was laid off from her job in sales support at a tech-related company in late 2023, after the firm shifted jobs overseas. She voted for Kamala Harris last year.

She said while she knew presidents were often blamed for economic forces over which they had little control, she felt in this case Trump and his policies, like tariffs, were "shooting ourselves in the foot".

On Tuesday night, Trump called tariffs his "favourite word", pointing to hundreds of billions of dollars of US revenue from import taxes.

The White House blames Biden and the Fed, arguing high interest rates are hurting the economy.

The US central bank has twice reduced rates to about 3.9% and may cut them again on Wednesday.

Many Trump supporters have said they still back the president, despite feeling the pinch themselves.

John Mohring, 60, of Kenosha, Wisconsin, has backed Trump since 2016, though rising prices worry him.

Mr Mohring, who works in construction and has lived alone since his wife died three years ago, said grocery prices started rising before Trump returned to the White House "and it doesn't seem like it's going down".

He now typically spends $100 on groceries just for himself, even when avoiding buying meat and sticking with cheaper items.

Still, Mr Mohring said he backed the Trump administration's sweeping tariffs on imported goods and his border policies.

"I'm giving him the benefit of the doubt," Mr Mohring added.

Brad Smith, a corn and soybean farmer in north-western Illinois, was hurt earlier this year when China, previously a major buyer of US soybeans, froze its purchases amid a trade war with Washington.

But the market, he said, had been gradually recovering since late October, when the two countries reached a trade agreement and China resumed some purchases.

Trump on Monday also announced a $12bn aid package for US farmers.

Mr Smith said he still believed in Trump's plans for the economy, despite being getting caught in the crossfire.

"There's probably bigger things at play other than just the soybean and corn market," Mr Smith said.

"The whole America First idea is good."

Ukraine is "ready for elections", President Volodymyr Zelensky has said, after US President Donald Trump repeated claims Kyiv was "using war" to avoid holding them.

Zelensky's five-year term as president was due to end in May 2024, but elections have been suspended in Ukraine since martial law was declared after Russia's invasion.

Speaking to reporters following Trump's comments in a wide-raging Politico interview, Zelensky said he would ask for proposals to be drawn up which could change the law.

Elections could be held in the next 60 to 90 days if security for the vote was guaranteed with the help of the US and other allies, he said.

"I'm asking now, and I'm stating this openly, for the US to help me, perhaps together with our European colleagues, to ensure security for the elections," he told reporters.

"The issue of elections in Ukraine, I believe, depends first and foremost on our people, and this is a question for the people of Ukraine, not the people of other countries. With all due respect to our partners," he said.

"I've heard hints that we're clinging to power, or that I personally am clinging to the presidency" and "that's why the war isn't ending", which he called "frankly, a completely unreasonable narrative".

Russia has consistently claimed Zelensky is an illegitimate leader and demanded new elections as a condition of a ceasefire deal – a talking point which has been repeated by Trump.

"They talk about a democracy, but it gets to a point where it's not a democracy anymore," the US president told Politico. He has suggested without evidence that Zelensky is the main obstacle to peace as US-led efforts to broker a peace deal to end the war in Ukraine continue.

Such a vote would only be fair if all Ukrainians could participate, including soldiers fighting on the front line, a Ukrainian opposition MP told the BBC.

"In order for these elections to be fair all of the People of Ukraine would need to be allowed to vote," Lesia Vasylenko told the BBC World Service's Newsday programme.

She said that "elections are never possible in wartime", alluding to the suspension of elections in the UK during World War Two.

Discussions around holding elections have made headlines since Russia's full-scale invasion of Ukraine in 2022. They have been routinely dismissed by Ukraine's government, opposition and public alike, arguing unity in the war effort must come first.

A poll by the Kyiv International Institute of Sociology (KIIS) in March found about 78% of people opposed holding elections even after a complete settlement of the war.

"Even a year ago, Zelensky said that he was ready for elections as soon as the conditions allow" in the face of previous pressure, Hanna Shelest, a foreign policy analyst with the think tank Ukrainian Prism, told the BBC.

The question was, however, how to create the conditions Zelensky outlined, Shelest told the Newsroom programme on the BBC World Service, given there were around one million soldiers and four million refugees who would be voting - as well as unsecured areas in the country and ongoing strikes.

"You cannot guarantee the security of the polling stations," she said.

The US has asked Thailand and Cambodia to "cease hostilities immediately" as border clashes extended for a third day, killing at least 10 people and displacing hundreds of thousands.

The two nations must follow de-escalatory measures outlined in a peace accord brokered by US President Donald Trump in October, Secretary of State Marco Rubio said.

Trump has also said that he would "make a phone call" to stop the fighting, which is the most serious escalation since clashes in July killed dozens of people.

Both countries have blamed each other for re-igniting the fighting, which has seen air strikes and exchanges of artillery fire.

The death toll over three days of hostilities stands at 10 - seven from Cambodia and three from Thailand. Thai officials said they evacuated more than 400,000 people, while Phnom Penh said 100,000 on the Cambodian side have been moved to shelters.

Thailand's defence ministry said Wednesday military actions were "limited in scope and employed as a last option".

"Peace must come with the safety and security of our citizens, full stop," the ministry's spokesman said.

Cambodia on the other hand accused Thailand of launching "aggressive military attacks" that targeted civilian institutions and "sacred cultural sites", including historic temples along the disputed border.

Also on Wednesday, Cambodia announced it was pulling out from the South East Asian Games that is being hosted in Thailand.

The Cambodian National Olympic Committee cited "serious concerns and requests" from the families of its athletes for the withdrawal. It added that the decision was "not made lightly".

United Nations' Secretary-General António Guterres urged both sides to "exercise restraint and avoid further escalation", noting how their dispute has led to "significant civilian casualties, damage to civilian infrastructure, and displacement on both sides".

The century-old border dispute between the South East Asian neighbours dramatically escalated on 24 July with a Cambodian rocket barrage into Thailand, followed by Thai air strikes.

That set off five days of intense fighting, which left dozens of soldiers and civilians dead. Later that month, Bangkok and Phnom Penh agreed to an "immediate and unconditional ceasefire" brokered by Malaysian Prime Minister Anwar Ibrahim and Trump - who at the time threatened to stop tariff negotiations until the hostilities stopped.

In October, Trump claimed a historic achievement in ending the border conflict after both sides signed a ceasefire agreement, but tensions have continued to simmer.

Violence this week has expanded into at least six provinces in north-eastern Thailand and five provinces in Cambodia's north and north-west.

Thailand and Cambodia have been contesting territorial sovereignty along their 800km land border for more than a century, since the borders of the two nations were drawn after the French occupation of Cambodia.

This week, several countries, including the UK, US and Japan, have issued warnings against travelling to the border areas citing the renewed fighting.

South Korea has lodged a complaint with the Chinese and Russian defence attaches based in the country, a day after their warplanes entered its air defence zone.

Seoul said it sent up fighter jets to "take tactical measures in preparation for any emergencies" after seven Russian and two Chinese military aircraft "briefly entered" the zone on Tuesday, but noted they "did not violate" South Korea's airspace.

Some countries delineate air identification defence zones, wherein they require foreign planes to identify themselves. These are not part of sovereign airspaces under international law.

In March this year, Seoul also deployed fighter jets after several Russian warplanes flew into the zone.

The Russian aircraft entered Korea's Air Defense Identification Zone (Kadiz) near Ulleung Island and Dokdo, while the Chinese aircraft entered near Ieodo, a Joint Chiefs of Staff official said, according to South Korean media.

Both sides' aircraft then regrouped in the airspace near Japan's Tsushima Island, the official said.

"Our military will actively respond to aircraft activities from neighbouring countries in the Kadiz in compliance with international law," South Korea's defence ministry said on Wednesday when lodging the complaint.

Both Japan and South Korea have laid claims to the Dokdo island grouping, as has North Korea.

Ieodo - a submerged rock above the South Korean island of Jeju - is a point of dispute between Seoul and Beijing, each of whom have included it in their air defence zones.

China on Wednesday confirmed that its air force had conducted a joint patrol with Russia in the East China Sea and Western Pacific airspace.

The exercise was part of an "annual cooperation plan" between Beijing and Moscow to "address regional challenges and maintain regional peace and stability", said a national defence spokesman.

China and Russia have entered South Korea's air defence zone without notification on several occasions since 2019, often during similar exercises.

Russia does not recognise South Korea's air defence zone, describing it as "unilaterally" established and saying it should therefore not create any legal obligations for other countries.

A sperm donor who unknowingly harboured a genetic mutation that dramatically raises the risk of cancer has fathered at least 197 children across Europe, a major investigation has revealed.

Some children have already died and only a minority who inherit the mutation will escape cancer in their lifetimes.

The sperm was not sold to UK clinics, but the BBC can confirm a "very small" number of British families, who have been informed, used the donor's sperm while having fertility treatment in Denmark.

Denmark's European Sperm Bank, which sold the sperm, said families affected had their "deepest sympathy" and admitted the sperm was used to make too many babies in some countries.

The investigation has been conducted by 14 public service broadcasters, including the BBC, as part of the European Broadcasting Union's Investigative Journalism Network.

The sperm came from an anonymous man who was paid to donate as a student, starting in 2005. His sperm was then used by women for around 17 years.

He is healthy and passed the donor screening checks. However, the DNA in some of his cells mutated before he was born.

It damaged the TP53 gene – which has the crucial role of preventing the body's cells turning cancerous.

Most of the donor's body does not contain the dangerous form of TP53, but up to 20% of his sperm do.

However, any children made from affected sperm will have the mutation in every cell of their body.

This is known as Li Fraumeni syndrome and comes with an up to 90% chance of developing cancer, particularly during childhood as well as breast cancer later in life.

"It is a dreadful diagnosis," Prof Clare Turnbull, a cancer geneticist at the Institute of Cancer Research in London, told the BBC. "It's a very challenging diagnosis to land on a family, there is a lifelong burden of living with that risk, it's clearly devastating."

MRI scans of the body and the brain are needed every year, as well as abdominal ultrasounds, to try to spot tumours. Women often choose to have their breasts removed to lower their risk of cancer.

The European Sperm Bank said the "donor himself and his family members are not ill" and such a mutation is "not detected preventatively by genetic screening". They said they "immediately blocked" the donor once the problem with his sperm was discovered.

Children have died

Doctors who were seeing children with cancer linked to sperm donation raised concerns at the European Society of Human Genetics this year.

They reported they had found 23 with the variant out of 67 children known at the time. Ten had already been diagnosed with cancer.

Through Freedom of Information requests and interviews with doctors and patients we can reveal substantially more children were born to the donor.

The figure is at least 197 children, but that may not be the final number as data has not been obtained from all countries.

It is also unknown how many of these children inherited the dangerous variant.

Dr Edwige Kasper, a cancer geneticist at Rouen University Hospital, in France, who presented the initial data, told the investigation: "We have many children that have already developed a cancer.

"We have some children that have developed already two different cancers and some of them have already died at a very early age."

Céline, not her real name, is a single-mother in France whose child was conceived with the donor's sperm 14 years ago and has the mutation.

She got a call from the fertility clinic she used in Belgium urging her to get her daughter screened.

She says she has "absolutely no hard feelings" towards the donor but says it was unacceptable she was given sperm that "wasn't clean, that wasn't safe, that carried a risk".

And she knows cancer will be looming over them for the rest of their lives.

"We don't know when, we don't know which one, and we don't know how many," she says.

"I understand that there's a high chance it's going to happen and when it does, we'll fight and if there are several, we'll fight several times."

The donor's sperm was used by 67 fertility clinics in 14 countries.

The sperm was not sold to UK clinics.

However, as a result of this investigation the authorities in Denmark notified the UK's Human Fertilisation and Embryology Authority (HFEA) on Tuesday that British women had travelled to the country to receive fertility treatment using the donor's sperm.

Those women have been informed.

Peter Thompson, the chief executive of the HFEA, said a "very small number" of women were affected and "they have been told about the donor by the Danish clinic at which they were treated".

We do not know if any British women had treatment in other countries where the donor's sperm was distributed.

Concerned parents are advised to contact the clinic they used and the fertility authority in that country.

The BBC is choosing not to release the donor's identification number because he donated in good faith and the known cases in the UK have been contacted.

There is no law on how many times a donor's sperm can be used worldwide. However, individual countries do set their own limits.

The European Sperm Bank accepted these limits had "unfortunately" been breached in some countries and it was "in dialogue with the authorities in Denmark and Belgium".

In Belgium, a single sperm donor is only supposed to be used by six families. Instead 38 different women produced 53 children to the donor.

The UK limit is 10 families per donor.

'You can't screen for everything'

Prof Allan Pacey, who used to run the Sheffield Sperm Bank and is now the deputy vice president of the Faculty of Biology Medicine and Health at the University of Manchester, said countries had become dependent on big international sperm banks and half the UK's sperm was now imported.

He told the BBC: "We have to import from big international sperm banks who are also selling it to other countries, because that's how they make their money, and that is where the problem begins, because there's no international law about how often you can use the sperm."

He said the case was "awful" for everybody involved, but it would be impossible to make sperm completely safe.

"You can't screen for everything, we only accept 1% or 2% of all men that apply to be a sperm donor in the current screening arrangement so if we make it even tighter, we wouldn't have any sperm donors – that's where the balance lies."

This case, alongside that of a man who was ordered to stop after fathering 550 children through sperm donation, has again raised questions over whether there should be tougher limits.

The European Society of Human Reproduction and Embryology has recently suggested a limit of 50 families per donor.

However, it said this would not reduce the risk of inheriting rare genetic diseases.

Rather, it would be better for the wellbeing of children who discover they are one of hundreds of half-siblings.

"More needs to be done to reduce the number of families that are born globally from the same donors," said Sarah Norcross, the director of the Progress Educational Trust, an independent charity for people affected by infertility and genetic conditions.

"We don't fully understand what the social and psychological implications will be of having these hundreds of half siblings. It can potentially be traumatic," she told BBC News.

The European Sperm Bank said: "It is important, especially in light of this case, to remember that thousands of women and couples do not have the opportunity to have a child without the help of donor sperm.

"It is generally safer to have a child with the help of donor sperm if the sperm donors are screened according to medical guidelines."

What if you are considering using a sperm donor?

Sarah Norcross said these cases were "vanishingly rare" when you consider the number of children born to a sperm donor.

All of the experts we spoke to said using a licensed clinic meant the sperm would be screened for more diseases than most fathers-to-be are.

Prof Pacey said he would ask "is this a UK donor or is this a donor from somewhere else?"

"If it's a donor from somewhere else I think it's legitimate to ask questions about has that donor been used before? Or how many times will this donor be used?"

If you or someone you know has been affected by the issues raised, details of help and support are available at BBC Action Line.
