The head of the global nuclear watchdog says there has been no further damage to Iran's Natanz uranium enrichment plant since Israel struck the country's nuclear sites on Friday.

Rafael Grossi told the International Atomic Energy Agency's (IAEA) board of governors that an above-ground enrichment facility at Natanz was destroyed, but that there were no signs of a physical attack at the underground facility there.

Four buildings were also damaged at the Isfahan site, he said, including a uranium conversion plant, and no damage was visible at the underground Fordo enrichment plant.

Israel said it attacked the sites and killed nine nuclear scientists to stop Iran developing nuclear weapons.

It alleged that Iran had in recent months "taken steps to weaponize" its stockpile of enriched uranium, which can be used to make fuel for power plants but also nuclear bombs.

On Sunday, Iran reiterated that its nuclear programme was peaceful and urged IAEA's 35-nation board to strongly condemn the Israeli strikes.

Grossi briefed the board on Monday that the IAEA had been monitoring the situation in Iran very carefully, ascertaining the status of the country's nuclear facilities and assessing radiation levels through communication with local authorities.

He said Friday's attack on Natanz destroyed the above-ground part of the Pilot Fuel Enrichment Plant (PFEP), where cascades of centrifuge were producing uranium enriched up to 60% purity - close to the 90% required for weapons-grade uranium

Electricity infrastructure at Natanz, which included an electrical sub-station, a power supply building, and emergency generators, were also destroyed.

"There has been no indication of a physical attack on the underground cascade hall containing part of the PFEP and the main Fuel Enrichment Plant. However, the loss of power to the cascade hall may have damaged the centrifuges there," Grossi added.

He also said there was radiological and chemical contamination at the site, but that the level of radioactivity outside had remained unchanged and at normal levels.

The Israeli military said on Friday that the underground centrifuge hall was also damaged as part of the attack on Natanz, but it provided no evidence.

The IAEA chief said four buildings were damaged in a separate attack on Friday on the Isfahan Nuclear Technology Centre - the central chemical laboratory, a uranium conversion plant, the Tehran reactor fuel manufacturing plant, and a facility to convert uranium hexafluoride to uranium metal, which was under construction.

As at Natanz, off-site radiation levels remain unchanged, he added.

The Israeli military said on Friday that the Isfahan strike "dismantled a facility for producing metallic uranium, infrastructure for reconverting enriched uranium, laboratories, and additional infrastructure".

On Saturday, Iran's semi-official Isna news agency quoted spokesman of the Atomic Energy Organization of Iran (AEOI) as saying there was "limited damage to some areas at the Fordo enrichment site" following an Israeli attack.

However, the Israeli military has not confirmed carrying out any strikes there.

Grossi said no damage had been seen at Fordo, or at the Khondab heavy water reactor, which is under construction.

He urged all parties to exercise maximum restraint, warning that military escalation threatened lives and increased the chance of a radiological release with serious consequences for people and the environment.

Iranian Foreign Minister Abbas Araghchi told foreign diplomats in Tehran on Saturday that Israel's attacks on his country's nuclear facilities were a "blatant violation of international law", and that he hoped the IAEA's board would issue a strong condemnation.

He also said that Iran's missile strikes on Israel since Friday were a "response to aggression".

The Israeli military's spokesperson, Brig Gen Effie Defrin said on Monday that its large-scale air campaign would "continue to act in pursuit of the operation's objective, to neutralize the existential threat from Iran, from its nuclear project to the regime's missile array".

Iran's health ministry says Israeli strikes have killed more than 220 people since Friday. Twenty-four Israelis have been killed by Iranian missiles, according to Israeli authorities.

Last Thursday, the IAEA's board formally declared Iran in breach of its non-proliferation obligations for the first time in 20 years. A resolution said Iran's "many failures" to provide the agency with full answers about its undeclared nuclear material and nuclear activities constituted non-compliance.

Under a 2015 nuclear deal with world powers, Iran was not permitted to enrich uranium above 3.67% purity - the level required for fuel for commercial nuclear power plants - and was not allowed to carry out any enrichment at Fordo for 15 years.

However, US President Donald Trump abandoned the agreement during his first term in 2018, saying it did too little to stop a pathway to a bomb, and reinstated US sanctions.

Iran retaliated by increasingly breaching the restrictions - particularly those relating to enrichment. It resumed enrichment at Fordo in 2021 and has amassed enough 60%-enriched uranium to potentially make nine nuclear bombs, according to the IAEA.

A man who is accused of killing a Democratic state lawmaker and her husband, and injuring another state lawmaker and his wife, allegedly attempted to kill two other state lawmakers, Minnesota officials said on Monday.

Vance Luther Boelter, 57, who is charged with fatally shooting Melissa Hortman, a Minnesota Democrat, and her husband, Mark, visited the homes of three other state lawmakers in "truly chilling" attacks, US Attorney Joseph H Thompson said.

Mr Boelter, who police said researched the victims and their families beforehand, allegedly had planned for a larger scale attack, which police thwarted.

He appeared in court on Monday afternoon to face six federal charges, and possibly the death penalty, if he is found guilty.

Mr Boelter was wearing an orange jumpsuit when he arrived in court in St. Paul on Monday afternoon. He said he cannot afford a lawyer and will have a federal defence lawyer.

At the brief hearing, Mr Boelter said he has seven cars, $20,000-30,000 in savings and makes about $540 per week.

At a press conference on Monday officials walked through the early hours of Saturday morning in the suburbs of Minneapolis when the Hortmans were killed, and John Hoffman, a Minnesota state senator, and his wife, Yvette Hoffman, were shot multiple times.

They also announced that Mr Boelter faces six federal charges, some of which make him eligible for the death penalty. At the federal level, he faces two counts of stalking, two counts of murder, and two firearms-related charges.

Separately, at the state level Mr Boelter is charged with two counts of second-degree murder and two counts of attempted second-degree murder at the state level.

Thompson said that Mr Boelter arrived at the Hoffman home disguised as a police officer in a large black car with emergency lights on the vehicle. Mr Boelter was wearing a "hyper realistic silicon mask" when he rang the doorbell and shouted "this is the police, open the door".

Thompson said authorities have a clear picture of what happened because the Hoffmans have a security camera outside their front door.

When the Hoffmans opened the door, Mr Boelter shined a flashlight at the couple. Mr Boelter told the couple there was a shooting reported in the house and lowered his flashlight, Thompson said. The couple then realized he was not a police officer.

After they attempted to push him out, he allegedly fired at the couple multiple times, Thompson said, then fled the scene and the couple's daughter Hope called 911.

Yvette Hoffman was shot eight times and John Hoffman was shot nine times. Both remain in hospital, though Minnesota Governor Tim Walz has said they are expected to make a full recovery.

After allegedly shooting the Hoffmans, Mr Boelter drove to another state representative's home and rang the doorbell there, Thompson said.

That state representative was not home, Thompson said, noting that she and her family were on vacation. Authorities did not reveal her name.

He then drove to a third lawmaker's home, allegedly targeting them, Thompson said. Officials did not reveal the name of that state lawmaker, either.

Thompson said an officer pulled up next to Mr Boelter in his vehicle and assumed he was a police officer, dispatched to the scene to perform a wellness check on that lawmaker.

When the officer asked Mr Boelter what he was doing, he simply stared straight ahead, Thompson said, and Mr Boelter went on to the Hortman residence.

He is accused of arriving at the Hortman home, and allegedly shooting and killing Melissa and Mark Hortman. Police said they found him at that residence and engaged fire before Mr Boelter fled.

After he fled, police embarked on a two-day search for Mr Boelter before finding him late Sunday night in a wooded rural area west of Minneapolis, where he surrendered peacefully, eventually crawling towards officers, police said.

Thompson said Mr Boelter had "planned his attack carefully".

"He conducted surveillance of their homes and took notes about the location of their homes," he said of Boelter.

Upon finding his car, officials discovered five more firearms including assault-style rifles, large quantities of ammunition and a list of more than 45 Minnesota state and federal elected officials, including Melissa Hortman.

Mark Bruley, police chief from Brooklyn Park, Minnesota, said the officers who arrived at the Hortman home "foiled" a larger plan. They "essentially took (Mr Boelter's) vehicle away from him, which involved all his maps, all his names, all his weaponry", Mr Bruley said.

"I would be very scared what it would look like over the next few hours ahead had we not done that," he said.

"It's a chilling attack on our democracy, on our way of life," Thompson said at the Monday press conference. "It's only the most recent example of violent political extremism in this country, and that's a trend that's been increasing over in recent years, and that's unfortunate.

I hope it is a wake up call to everyone that people can disagree with you without being evil or needing to be killed or hurt."

Mr Boelter is scheduled to return to court for his next hearing 27 June.

At least 22 Palestinians have been killed by Israeli gunfire near aid distribution sites operated by the US-backed Gaza Humanitarian Foundation, the Hamas-run Gaza health ministry said.

The Israel Defense Forces (IDF) told the BBC that it was examining the reports.

Hundreds of Palestinians have been killed trying to get food from the GHF sites, opened by Israel after it partially lifted a three-month blockade which the UN said had pushed the Gazan population to the brink of starvation.

UN human rights chief Volker Turk said: "Israel's means and methods of warfare are inflicting horrifying, unconscionable suffering on Palestinians in Gaza."

Addressing the UN Human Rights Council on Monday, he accused Israel of weaponising food and repeated his call for a full investigation into the attacks near the sites. UN agencies have refused to work with the GHF.

On several previous occasions the IDF has acknowledged that its troops opened fire near aid sites.

The health ministry said 20 were killed on Monday at the GHF centre at al-Alam in the southern city of Rafah, while rescuers reported two killed at a GHF site in the central Netzarim corridor.

Many of those killed and injured at al-Alam were taken to Nasser hospital in nearby Khan Younis, where relatives gathered. Many were buried in the hours after their arrival, in line with Islamic tradition.

Ahmed Alfara, a doctor at the hospital, told the Reuters news agency that the distribution system had failed "100%".

"No one can get that distribution, that aid, no one can get it," he said.

"We have to recognise that [UN humanitarian agency] Unrwa and NGOs must again get that distribution and try to redistribute it for the Palestinian people."

He reported that many of the casualties on Monday had suffered gunshot wounds, including to the head.

Ahmed Fayad, who attempted to get food from the GHF site on Monday, described the GHF operation as a "trap".

"We went there thinking we would get aid to feed our children, but it turned out to be a trap, a killing. I advise everyone: don't go there," he told Reuters.

Al-Alam has been the scene of several similar deadly incidents since the new Israeli-backed food distribution system began operating.

Before Monday's incident, the health ministry in the Hamas-run Gaza Strip said that at least 300 people had been killed and more than 2,600 wounded near aid distribution sites since the GHF began operations in Gaza on 26 May.

The IDF has contested the death toll and said Hamas had caused much of the violence.

Israel does not allow international news organisations including the BBC into Gaza, making verifying what is happening in the territory difficult.

It has been 20 months since Israel launched a military campaign in Gaza in response to the Hamas-led cross-border attack on Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.

At least 55,297 people have been killed in Gaza since then, according to the territory's health ministry.

Long queues at petrol stations and bakeries. Long lines of cars trying to escape the capital. And long, frightening nights.

Residents of Tehran - still shocked by Israel's sudden attack on Iran in the early hours of Friday morning - speak of fear and confusion, a feeling of helplessness and conflicting emotions.

"We haven't slept for nights," a 21-year-old music student told me over an encrypted social media app.

"Everyone is leaving but I'm not. My dad says it's more honourable to die in your own house than to run away."

'Donya' - she doesn't want to reveal her real name - is one of many Iranians now caught in a war between a regime she loathes and Israel, whose destructive power in Gaza she has witnessed on screen from afar.

"I really don't want my beautiful Tehran to turn into Gaza," she said.

As for Israeli Prime Minister Benjamin Netanyahu's call on Iranians to rise up against their clerical leadership, she has a firm response.

"We don't want Israel to save us. No foreign country ever cared for Iran," she said. "We also don't want the Islamic Republic."

Another woman said that at first she had felt a "strange excitement" to see Israel kill Iranian military officials so powerful that she thought they would live for ever.

"Suddenly that image of power was shattered," she told BBC Persian.

"But from the second day, when I heard that regular people - people I didn't know, people like me - had also been killed, I started to feel sorrow, fear and sadness."

And she said her sadness turned to anger when she heard that the South Pars gas field had been hit, fearing that Israel was trying to turn Iran "into ruins".

For the first time in her life, she said, she has started to prepare for the idea of dying.

More than 220 people - many of them women and children - have been killed since Friday, according to the Iranian authorities.

Israeli authorities say Iranian missiles have killed at least 24 people in Israel over the same period.

Unlike in Israel, there are no warnings of imminent attacks in Iran, and no shelters to run to.

Even some supporters of the regime are reported to be upset that its much-vaunted defences have been so thoroughly exposed.

And, among many Iranians, distrust in the authorities runs deep.

Donya used to defy the regime and its strict dress code by going out with her hair uncovered.

Now, with her university exams postponed until next week, she's staying at home.

"I get so terrified at night," she said. "I take some pills to help me relax and try to sleep."

The Iranian government has suggested that people shelter in mosques and metro stations.

But that is hard, when the explosions seem to come out of nowhere.

"Tehran is a big city and yet every neighbourhood has been somehow affected by the damage," another young woman told BBC Persian.

"For now, all we do is check the news every hour and call the friends and relatives whose neighbourhood has been hit to make sure they are still alive."

She and her family have now left their home to stay in an area where there are no known government buildings.

But you never know, in a country like Iran, who may be living next to you.

The Israeli assault has divided Iranians, she said, with some celebrating the regime's losses, while others are angry at those cheering Israel on.

Many Iranians keep changing their minds about what they think. Divisions are bitter, even among some families.

"The situation feels like the first hours after the Titanic hit the iceberg," the woman said.

"Some people were trying to escape, some were saying it wasn't a big deal, and others kept dancing."

She has always protested against Iran's clerical rulers, she told the BBC, but sees what Netanyahu is doing to her country as "inexcusable".

"Everyone's life, whether they supported the attacks or not, has been changed forever.

"Most Iranians, even those who oppose the government, have now realised that freedom and human rights don't come from Israeli bombs falling on cities where defenceless civilians live."

She added: "Most of us are scared and worried about what's coming next. We've packed bags with first aid supplies, food, and water, just in case things get worse."

Israel says the Iranian armed forces have deliberately placed their command centres and weapons inside civilian buildings and areas.

Members of Iran's large diaspora are also worried.

"It's hard to convey what it's like to be an Iranian right now," says Dorreh Khatibi-Hill, a Leeds-based women's rights activist and researcher who is in touch with family, friends and other anti-regime activists.

"You're happy that members of the regime - who have been torturing and murdering people - are being taken out.

"But we know that civilians are dying. This is a devastating humanitarian disaster."

And Iranians are not being given accurate information on what is happening, she says.

"The main person in Iran - the supreme leader - is still alive while Iranians are fleeing for their lives," she adds.

"No one wants Iran to turn into another Iraq, Syria or Afghanistan. None of us wants this war. We don't want the regime either."
