A day of high drama has drawn to an end in South Korea, with investigators suspending an attempt to arrest ousted President Yoon Suk Yeol after a six-hour standoff with the security team outside his home.

"We've determined that the arrest is impossible," said the Corruption Investigation Office (CIO), which has been investigating Yoon's short-lived martial law declaration.

"Next steps will be decided after review," the CIO said, adding that Yoon's "refusal of the legal process" is "deeply regrettable".

Yoon's supporters, who have been camped out in front of the presidential residence for days, cheered in song and dance as the suspension was announced. "We won," they chanted.

Investigators have until 6 January to arrest Yoon, before the warrant expires. However they can apply for a new warrant and try to detain him again.

A US court has rejected the Biden administration's bid to restore "net neutrality" rules, finding that the federal government does not have the authority to regulate internet providers like utilities.

It marks a major defeat for so-called open internet advocates, who have long fought for protections that would require internet providers such as AT&T to treat all legal content equally.

Such rules were first introduced by the Federal Communications Commission under former Democratic president Barack Obama but later repealed during Republican Donald Trump's first term.

The decision, just as Trump is poised to enter the White House for a second term, likely puts an end to the long-running legal battle over the issue.

In their decision, the judges noted that different administrations have gone back and forth on the issue.

But they said the court no longer had to give "deference" to the FCC's reading of the law, pointing to a recent Supreme Court decision that limits the authority of federal agencies to interpret laws, a decision that critics expect will be used to weaken regulation in the years ahead.

"Applying Loper Bright, means we can end the FCC's vacillations," the Sixth Circuit Court of Appeals said.

Brendan Carr, a Republican member of the FCC who Trump has tapped to lead the agency, said he was pleased the court had invalidated the Biden administration's "Internet power grab".

The FCC's outgoing Democratic commissioner said the ruling turned the issue over to Congress.

"Consumers across the country have told us again and again that they want an internet that is fast, open, and fair," Jessica Rosenworcel said.

"With this decision it is clear that Congress now needs to heed their call, take up the charge for net neutrality, and put open internet principles in federal law."

The fight over net neutrality was once a heated issue in the US, pitting internet providers against big tech companies such as Google and Netflix.

Comedian John Oliver famously urged his audience to express support for the rules, leading to a deluge of comments that crashed the government's site.

But the issue has faded in prominence since the rules were repealed in 2018.

Thursday's ruling does not affect state-level net neutrality laws, which in some places offer similar protections.

But advocates, like Mr Oliver, have said that national rules are important to preventing internet providers from having powers to throttle certain content or charge more for speedy delivery of their service.

Public Knowledge, a progressive-leaning internet policy group, said the decision had weakened the FCC's power to shape privacy protections, implement public safety measures and take other action.

It said it believed the court had erred in ruling that internet service providers were simply offering an "information service" rather than acting as telecommunications companies.

"The court has created a dangerous regulatory gap that leaves consumers vulnerable and gives broadband providers unchecked power over Americans' internet access," it said.

But USTelecom, an industry group whose members include AT&T and Verizon, said the decision was "a victory for American consumers that will lead to more investment, innovation, and competition in the dynamic digital marketplace."

Security posts known as bollards were not in place before a suspect drove a truck into a crowd in the French Quarter of New Orleans early on New Year's Day, killing 14 and injuring at least 35.

Louisiana officials have said the street barriers were malfunctioning and were undergoing renovations before the city hosts the NFL Super Bowl on 9 February.

The short and sturdy posts - made of concrete, metal or other materials - are meant to block cars from entering pedestrian areas.

Christopher Raia, a deputy assistant director with the FBI, on Thursday called the attack an act of terrorism.

During the early morning hours on New Year's Day, a police vehicle was parked at an intersection to block access to Bourbon Street in the French Quarter, where the attack took place, but the suspect drove around the car and onto the sidewalk, police said.

Police have named Shamsud-Din Jabbar, a 42-year-old Texas resident and US Army veteran, as the suspect. He died in the attack.

New Orleans Police Chief Anne Kirkpatrick said on Wednesday that police had been "aware of the bollard situation" and took steps to "harden those target areas".

"We did indeed have a plan, but the terrorist defeated it," she said.

Ms Kirkpatrick said the city planned to take a number of steps to increase security at the Sugar Bowl American football game, which was moved from Wednesday to Thursday afternoon because of the attack.

Bourbon Street will be re-opened on Thursday shortly ahead of the game.

"We have re-enforced the area," Louisiana Governor Jeff Landry said on Thursday.

New Orleans began placing bollards on Bourbon Street over ten years ago, Mayor LaToya Cantrell said on Wednesday.

But, she added, the bollards began to malfunction because of clogs from Mardi Gras beads, leading officials to try to replace them before the Super Bowl, which is scheduled to take place at the Caesars Superdome, near the site of the attack.

At the news conference, Ms Kirkpatrick defended the other security measures the city had in place.

"We did have a car there, we had barriers there, we had officers there, and they still got around," she said.

A number of cities in the US and around the world have installed bollards to prevent attacks.

New York City put the security measures in place along the Hudson River Park bike path after a man drove a rented pick-up truck into cyclists and runners along the path, killing eight people, in 2017.

It's too difficult to say for certain whether the New Orleans bollards being in place would have prevented such an incident, said University of Michigan professor and counterterrorism expert Javed Ali.

"He had a Ford 150 pick-up truck. You gun that thing at 50, 60 miles an hour, and who knows, even with bollards in place, would the car just - through physics - have rammed through them anyways?" he said.

"There must have been a lot of luck involved," Mr Ali added. "That's unfortunately what happens in these types of attacks."

A 2017 report commissioned by the city of New Orleans found the French Quarter was a "risk and target area for terrorism that the FBI has identified as a concern that the city must address".

The report noted that the neighbourhood was "often densely packed with pedestrians and represents an area where a mass casualty incident could occur".

Fans from two US universities filled a stadium in New Orleans for a highly anticipated American football game as the city reels from a New Year's Day attack.

The annual Sugar Bowl, which was scheduled to take place Wednesday, was postponed to Thursday at 15:00 local time (21:00 GMT) after a Texas man drove through a crowded New Orleans street, killing 14 people.

People gathered in the stadium partook in a moment of silence to remember the victims of Wednesday's attack.

The game brought thousands of fans to the city to see the University of Notre Dame take on the University of Georgia at the 70,000-seat Caesars Superdome.

Notre Dame's "Fighting Irish" ultimately emerged the winner, beating the Georgia Bulldogs 23-10.

Ahead of the game's start, Bourbon Street - where the attack took place on Wednesday - reopened to the public for the first time since the deadly event.

Yellow barriers, designed to prevent cars from driving onto the pavement, lined both sides of the street.

Fourteen flowers were laid against a wall at the spot where the attacker first drove into a crowd.

Many who trickled in had come to have a few drinks before heading over to the stadium for the game, with almost everyone wearing red for Georgia, and green or blue and gold for Notre Dame.

As the street reopened, a fan of the Notre Dame college football team yelled: "Go fighting Irish! We love life! So let's live!"

A New Orleans man who was discharged from the hospital on Thursday afternoon after being caught up in the attack, headed straight back to Bourbon Street dressed in the same clothes he was wearing on 1 January.

Speaking to the BBC, Jovon Miguel Bell lifted his shirt to show cuts and bruises across his torso, which he said were the result of getting trampled.

"I'm blessed, to be honest. God is good," he said. "Blessings to the victims and their families."

Mr Bell admitted he was "drunk as hell" at the time of the attack, but does vaguely remember what landed him in hospital.

"I'm walking down the street and I hear the screams. Ruckus. Chaos," he said. "As soon as I turn around, I got hit [by a person] and fall to the ground. I got stepped on, multiple times."

Now free from hospital, he headed straight back to the bars of Bourbon Street as the Sugar Bowl game was ongoing, where he said he felt lucky he escaped with minor injuries.

Ahead of the game, state authorities assured the public that the city had taken additional safety precautions.

Brian Williams, a Georgia supporter, told the BBC that "the bad guys would have won" if the game had been cancelled or further postponed after the attack.

"Nowhere will be safer than New Orleans now," he said, as he gestured at a small group of state troopers on Bourbon Street. "There's nothing to worry about."

Like other football fans in town for the game, Mr Williams said the mood was sombre when he arrived in town early Wednesday.

"It felt off. It felt weird to be out in town, and we couldn't even get to Bourbon Street," Mr Williams said. "But this place will be back to normal soon."

Master P, a New Orleans native and rap singer whose full name is Percy Robert Miller, visited Bourbon Street on Thursday to reassure local resident he would do whatever he could to help the city recover.

"We've got to show the people we're not stopping. We are going to move on," he said. "Even this evil stuff that came against us is not going to stop us."

Mr Miller described the city as one where people come to "celebrate" and described it as "our culture".

Jefferson County Sheriff Joseph Lopinto told reporters Thursday the college football match would be secure for fans who have come to the city.

"It's probably going to be one of the safest places in the country," Mr Lopinto said. "If my kid wanted to come to the game, I'd have no problem."

As the sun set over Bourbon Street on Thursday, many locals said they were confident that the vibrant area would bounce back quickly after the attack.

Among them was Darnell Simmons, a 23-year-old member of a brass band playing at the Bourbon House Oyster bar.

"A terrible thing happened here," he said. "But we're back, we're here to remember those we lost."

The bar's owner, Dickie Brennan, said he felt "incredibly emotional" to hear music return to Bourbon Street.

"We overcame Katrina. God knows how many hurricanes, oil spills, crime," he added, referring to the 2005 hurricane that left more than 1,300 dead. "One guy will not stop this beautiful city and special neighbourhood."

"This city is resilient. We have to be."

Just after 3:00 local time on 1 January officials say 42-year-old army veteran, Shamsud-Din Jabbar, killed 14 people and wounded dozens more when he drove a pick-up truck into crowds for the New Years holiday.

Before Jabbar was killed in a shoot-out with police during the attack, he had proclaimed his allegiance to the Islamic State group in videos uploaded to social media, according to the FBI.

The Sugar Bowl is watched by millions of Americans every year, traditionally on New Year's Day.

The game, along with the Los Angeles Rose Bowl, is a big tourist draw for the city.

The Sugar Bowl dates back to 1935, playing host to many of the best coaches, players and teams in college football history.

The Super Bowl, America's biggest sporting event, is scheduled for 9 February at the same New Orleans venue as the Sugar Bowl.

Heavy snow blends into white thick clouds in Skellefteå, a riverside city in northern Sweden that is home to 78,000 residents.

It's also the location of what was supposed to become Europe's biggest and greenest electric battery factory, powered by the region's abundance of renewable energy.

Swedish start-up Northvolt opened its flagship production plant here in 2022, after signing multi-billion euro contracts with carmakers including BMV, Volkswagen and Nordic truck manufacturer Scania.

But it ran into major financial troubles last year, reporting debts of $5.8bn (£4.6bn) in November, and filing for bankruptcy in the US, where it had been hoping to expand its operations.

Since September it's laid off around a quarter of its global workforce including more than 1,000 staff in Skellefteå.

"A lot of people have moved out already," says 43-year-old Ghanaian Justice Dey-Seshie, who relocated to Skellefteå for a job at Northvolt, after previously studying and working in southern Sweden.

"I need to secure a job in order to extend my work permit. Otherwise, I have to exit the country, sadly."

Many researchers and journalists tracking Northvolt's downfall share the view that it was at least partly caused by a global dip in demand for electric vehicles (EVs).

In September Volvo abandoned its target to only produce EVs by 2030, arguing that "customers and markets are moving at different speeds". Meanwhile China, the market leader in electric batteries, has been able to undercut Northvolt's prices.

Missing production targets (a key factor in BMW pulling out of a €2bn deal in June), expanding too quickly, and the company's leadership have also been widely cited as factors fuelling the crisis.

"To build batteries is a very complex process. It takes a lot of capital, it takes time, and they obviously just didn't have the right personnel running the company," argues Andreas Cervenka, a business author and economics commentator for Swedish daily Aftonbladet.

At Umeå university, Madeleine Eriksson, a geographer researching the impact of so-called "green industries" says Northvolt presented a "save the world mentality" that impressed investors, media and local politicians.

But this "now-or-never" approach, she argues, glossed over the fact it was a risk-taking start-up that "never finished attracting investment".

Northvolt did not respond to multiple requests from the BBC to respond to comments about its downfall or future plans.

The firm has hired German Marcus Dangelmaier, from global electronics company TE Connectivity to run Northvolt's operations in Skellefeå, from January, as it seeks to attract fresh investment.

Northvolt's co-founder and CEO Peter Carlsson – a former Tesla executive – resigned in November.

• Listen Business Daily: Crisis at Northvolt

As the postmortem into the crisis continues, there are debates about the potential impact on Sweden's green ambitions.

Northern Sweden, dubbed the "Nordic Silicon Valley of sustainability" by consultancy firm McKinsey, has swiftly gained global reputation for new industries designed to fast-track Europe's green transition.

The region is a hub for biotech and renewable energy. Alongside Northvolt, high profile companies include Stegra (formerly called H2 Green Steel) and Hybrit, which are both developing fossil-free fuel using hydrogen.

But Mr Cervenka, the economics commentator, argues Northvolt's downfall has damaged Sweden's "very good brand" when it comes to green technologies.

"There was a huge opportunity to build this champion, and to build this Swedish icon, but I think investors that lost money are going to be hesitant to invest again in a similar project in the north of Sweden," he says.

Some local businesses say the publicity around Northvolt's crisis is already having a negative impact.

"I feel it myself when I travel now – even to the southern parts of Sweden – and abroad, that people really ask me questions," says Joakim Nordin, CEO of Skellefteå Kraft, a major hydropower and wind energy provider, which was an early investor in Northvolt.

Headquartered in Malmö in southern Sweden, Cleantech for Nordics is an organisation that represents a coalition of 15 major investors in sustainability-focussed start-ups.

Here, climate policy analyst Eva Andersson believes the nation's long legacy as an environmental champion will remain relevant.

"I think it would be presumptuous to say that, okay, now we are doomed here in the Nordics because one company has failed," she argues.

Cleantech for Nordics' research suggests there were more than 200 investments in clean tech projects in Sweden in 2023.

Another study by Dealroom, which gathers data on start-ups indicates 74% of all venture capital funding to Swedish start-ups went to so-called impact companies which prioritise environmental or social sustainability, compared to a European average of just 35%.

"Sweden is still punching above its weight in this sector. And I think we could expect it to continue to do so moving forward as well," predicts Anderson.

There are growing calls for increased state support to help Sweden maintain its position. The Swedish government refused to bail out Northvolt, suggesting all startups – sustainable or not – should be subject to market forces rather than bailed out by taxpayers. But as other parts of the world ramp up battery production and other carbon-cutting industries, the decision has faced a backlash.

"The US and China have massive support packages for green industry, and they definitely are catching up and overtaking in some sectors. And so that is definitely a threat to be reckoned with," argues Andersson.

Just 3% of global battery cell production currently takes place in Europe - according to research for international consultancy firm McKinsey - with Asian firms leading the market.

Sweden's minister for Energy, Business and Industry Ebba Busch argues more EU support rather than funding from individual governments is the answer.

Last month she told Swedish television the situation at Northvolt was "not a Swedish crisis", rather a reflection of a Europe-wide challenge when it comes to competitiveness in the electric battery sector.

But while the government insists it wants Sweden to play a key role in Europe's battery industry, and the wider green transition, it has been accused of sending mixed messages. The right-wing coalition, which came into power in 2022 has cut taxes on petrol and diesel, and abolished subsidies for EVs.

"This is a very politically sensitive area," says journalist Cervenka. "The Swedish government is being actually criticised internationally for not fulfilling its climate obligations. And that is a stark contrast to the image of Sweden as a pioneer."

The BBC approached Busch's media team, but was not granted an interview.

Back in Skellefteå, where it has been dark since just after lunch, Joachim Nordin is preparing to commute home in the snow.

He says there's a strong industrial will for Sweden to remain a green tech role model, despite policymakers being "not as ambitious" as previous administrations.

The criteria that enticed Northvolt to establish its first factory in Skellefteå will also attract other big global players to the region, according to the energy company CEO.

"It's 100% almost renewable energy up here… and that's that's pretty unique if you compare it to the rest of Europe. But on top of that we are among the cheapest places in the world for the electricity prices. So if you combine those two things, it's a huge opportunity."

Skellefeå Kraft recently announced a collaboration with Dutch fuel company Sky NRG. Their ambition is to open a large factory by 2030, making fossil-free plane fuel (produced using hydrogen combined with carbon dioxide captured from biogenic sources).

"The publicity around Northvolt is not helping now, of course. But I hope that that's just something that will be remembered as a little bump in the road, when we look back at this 10 years from now," says Mr Nordin.
