Iranians ‘moved enriched uranium before US strikes'

Iran claims to have smuggled almost all of the country's highly enriched uranium to a secret location before the United States launched strikes on its nuclear bases.
Donald Trump dispatched seven B-2 stealth bombers from American soil to drop massive bunker-busting bombs on three enrichment facilities, Fordow, Natanz and Isfahan, on Saturday night, in an effort to pummel Tehran's nuclear programme.
Following the strikes, Mr Trump on Sunday said the US took the bomb 'right out of Iran's hands'.
In a post on Truth Social, he wrote: 'We had a spectacular military success yesterday, taking the 'bomb' right out of their hands.'
His defence secretary, Pete Hegseth, said Iran's nuclear ambitions had been 'obliterated'.
But officials believe that most of the material at Fordow, 400kg of 60 percent enriched uranium, had been moved elsewhere before the attack codenamed Operation Midnight Hammer.
Satellite images of convoys leaving all three sites in recent days appeared to support Iran's claims that it moved its 400kg stockpile – much of it previously held at Isfahan.
One image, released by Maxar Technologies, a US defence contractor, appeared to show a line of 16 trucks snaking down a road near to the entrance of the Fordow plant on June 19, which is concealed with earth and rubble.
Trucks, bulldozers and security convoys appeared to swarm Fordow, with analysts suggesting the image revealed a 'frantic effort' to move centrifuges or shielding materials, according to TS2 Space, a Polish defence firm.
Other images showed that Natanz, Iran's largest enrichment site, had already been damaged by extensive Israeli strikes.
This means Iran could still possess the material needed to develop a nuclear weapon, although this would be several years away and dependent on Tehran's ability to rebuild vital equipment.
Ronen Solomon, an Israeli intelligence analyst, told The Telegraph that even if Iran had moved its uranium, it would be 'like having fuel without a car', adding: 'They have the uranium, but they can't do a lot with it, unless they have built something we don't know about on a small scale.'
Ali Shamkhani, an adviser to the supreme leader, said: 'Even assuming the complete destruction of the sites, the game is not over, because enriched materials, indigenous knowledge, and political will remain intact.'
Uranium enrichment is the process of increasing the concentration of the uranium-235 isotope in natural uranium.
To build a nuclear weapon, uranium must be enriched to about 90 per cent U-235. Once enriched to that level, the material is considered 'weapons grade'.
Iran enriches uranium using centrifuges, which spin uranium hexafluoride gas at high speeds to separate the uranium isotopes, increasing the concentration of U-235.
This process, called centrifuge enrichment, is done in stages called cascades. Iran has been progressively installing more advanced centrifuges, like the IR-2m and IR-6 models, which are faster and more efficient than the older IR-1 centrifuges.
The more advanced the centrifuge, the faster and more efficiently it can separate uranium-235 from uranium-238 and in turn, speed up the time needed to make a nuclear bomb.
Iran's current centrifuge capacity could allow it to produce enough weapons-grade uranium for a bomb in less than two weeks, according to the Arms Control Association.
It is transported inside steel cylinders, specially designed to withstand significant pressure and temperature changes, according to the World Nuclear Association. The cylinders are then placed inside an extra level of protective casing, called an overpack, and can be transported via rail, road and sea.
Iran produces most of its near weapons-grade material at Fordow, its most heavily fortified nuclear facility, buried deep within a mountain, and considered a high-value target for America.
The base, reportedly shielded by half a mile of rock, could only be penetrated by the GBU-57 Massive Ordnance Penetrators or MOP, weapons experts said prior to the attack.
The bunker-busting MOPs are the largest and most powerful conventional bombs in the US arsenal.
As of May 17, Iran has amassed 408.6kg (900.8 pounds) of uranium enriched up to 60 per cent, a report by the International Atomic Energy Agency (IAEA) found.
It was an increase of 133.8kg (294.9 pounds), or almost 50 per cent, since the IAEA's last report in February.
JD Vance, the US vice-president, appeared to confirm the suggestion that the material had been moved at the 11th hour.
'We're going to work in the coming weeks to ensure that we do something with that fuel,' he told ABC News.
On Saturday, stealth pilots pummelled Iran's nuclear programme with 14 GBU-57 bombs, each weighing 30,000lbs, while a US submarine launched a further two dozen Tomahawk missiles.
In a televised address to the US a few hours later, Mr Trump said the strikes had 'completely and totally obliterated' three of Iran's nuclear sites – and warned of worse to come.
'This cannot continue. There will be either peace or there will be tragedy for Iran far greater than we have witnessed over the last eight days,' he added.
The full extent of the damage inside Fordow remains unclear.
At a news conference on Sunday, Gen Dan Caine, the chairman of the Joint Chiefs of Staff, said: 'Final battle damage will take some time, but initial battle damage assessments indicate that all three sites sustained extremely severe damage and destruction.'
Yet Two Israeli officials told the New York Times that their initial analysis suggested the fortified site at Fordow had sustained serious damage but had not been completely destroyed.
They also said Iran appeared to have moved equipment and uranium away from the site.
IAEA Director General Rafael Grossi told CNN that it was not yet possible to assess the damage done underground.
A senior Iranian source told Reuters that most of the highly enriched uranium at Fordow had been moved elsewhere before the attack. Reuters could not immediately corroborate the claim.

Any Iranian closure of Hormuz Strait would be 'extremely dangerous', EU's top diplomat says

BRUSSELS, June 23 (Reuters) - An Iranian closure of the Strait of Hormuz would be dangerous and "not good for anybody", the European Union's top diplomat said on Monday. "The concerns of retaliation and this war escalating are huge, especially closing of the Strait of Hormuz by Iran is something that would be extremely dangerous and not good for anybody," Kaja Kallas told reporters ahead of a meeting with EU foreign ministers. Iran's Press TV reported on Sunday that Iran's Supreme National Security Council needed to make a final decision on whether to close the strait, after parliament was reported to back the measure. About 20% of global oil and gas demand flows through the channel.

David Lammy refuses to say whether US attack on Iran was ‘right' or ‘legal'

Foreign secretary David Lammy has refused to defend Donald Trump 's attack on Iran and confirm it was either legal or even 'the right thing to do'. In an awkward interview on BBC Radio 4's Today Programme, Mr Lammy was asked four times if the attack on Iranian nuclear facilities was legal. It comes after Donald Trump's regime conducted airstrikes on three Iranian nuclear sites, despite Sir Keir Starmer pushing for de-escalation in the preceding days. The questions followed reports that UK attorney general Lord Hermer has suggested it would not be legal for the UK to launch such attacks. Radio 4 Today presenter Justin Webb asked him four times if the attack was legal with the foreign secretary avoiding the answer. 'We were not involved, it is for the Americans to discuss those legal issues," he responded repeatedly. The issue is important because of fears that it undermines the case against Russia's illegal invasion of Ukraine. However, Mr Lammy was not even able to answer whether the attack by US B-2 stealth bombers was even 'the right thing to do'. Mr Webb asked him: "Was the (US) military action the right thing to do?" Mr Lammy avoided the question, answering: "I've said that we weren't involved in the military action." Webb asked again: "Was it the right thing to do?" Lammy responded: "What I've said is that ultimately this can only be dealt with in diplomacy." The foreign secretary was not the only senior minister to refuse to answer difficult questions about the rapidly changing international crisis in the Middle East. Earlier, armed forces minister Luke Pollard claimed it is 'not for [him] to comment' on US action in the Middle East, refusing to say whether Britain is supportive of US strikes in Iran. Asked whether the UK was disappointed or pleased about the military intervention, Luke Pollard told Sky News: 'Well, it's not for me to comment on the particular US action, but we're assessing the battle damage at the moment to understand the true extent of the strikes. 'But our focus and the work that we are doing in conjunction with our US allies as well as those across Europe, is to put the pressure on the Iranian regime to get back to negotiating because a diplomatic solution is how we bring this crisis to an end.' When it was put to Mr Pollard that it was specifically his role to comment on military action around the world, he replied: 'I'm not going to be able to comment on that question, but what we can say is that we were not involved in the military action that the US took.' He added that Britain's focus was also on putting 'pressure on the Iranian regime to get back to negotiations because a diplomatic solution is how we bring this crisis to an end, with Iran not able to create a nuclear weapon, handing over their nuclear materials that they possess, and giving commitments that they won't threaten regional stability by developing a nuclear weapon in the future'. Over the weekend, the US attacked Fordo, Isfahan and Natanz which are linked to Iran's nuclear programme. Ahead of the strikes, the prime minister had been calling for calm, saying he has 'no doubt' that Mr Trump backs the G7's call for a de-escalation of tensions in the Middle East. It is understood there was no British involvement in the action but the government was informed before the US strikes. After the strikes took place, Sir Keir backed Mr Trump's administration describing Iran's nuclear programme as a 'grave threat to international security'. 'Iran can never be allowed to develop a nuclear weapon, and the US has taken action to alleviate that threat', he added. But he later warned there was a risk of the Middle East crisis spiralling beyond the region and urged all sides to return to negotiations.
