IAEA chief Rafael Grossi said that Iran’s enriched uranium is likely still being held at Iran’s Isfahan nuclear complex.

According to Grossi, the IAEA continues to get information through satellite images of the effects of US and Israeli airstrikes on Iran’s nuclear sites.
On June 9, 2025, just before the war started, images from an Airbus satellite showed a truck with 18 blue containers entering the Isfahan Nuclear Technology Center. The containers are believed to contain highly enriched uranium and have likely not been moved, AP stated.
Grossi emphasized that the current IAEA statements on Iran’s nuclear materials and the state of the nuclear sites can only be an estimate, as although Iran is required to open its nuclear facilities to IAEA inspection as a part of the Nuclear Non-Proliferation Treaty, the organization has not been able to visit the site.
“We haven’t been able to inspect or to reject that the material is there and that the seals, the IAEA seals, remain there. I hope that we’ll be able to do that, so what I tell you is our best estimate,” Grossi told AP.

In a UN press conference on Wednesday, Grossi said that an IAEA inspection was scheduled for a new uranium enrichment facility in Isfahan that Iran declared last June, but the strikes began on the date scheduled.
Russia offers to help with extraction of uranium
Grossi told AP that the IAEA has discussed the possibility of moving Iran’s enriched uranium out of the country with multiple parties, including Russia.
US President Donald Trump said that Russian President Vladimir Putin offered to help the US handle the enriched uranium, but that Trump had responded that Putin should be more “involved with ending the war with Ukraine.”
The IAEA has also been in discussions with the US and informally with Iran, AP stated, citing Grossi. However, the IAEA has not been part of the ceasefire negotiations in Pakistan, despite participating in the nuclear talks in February.

A senior Israeli military official said on Friday that if Iran’s stockpile of more than 400 kilograms of highly enriched uranium is not removed from the country in the wake of the recent war, the campaign could be considered “one big failure.”
Israeli officials have said that this stockpile is sufficient for 11 nuclear bombs if enriched further. Iran has long maintained that its program is peaceful, despite enriching uranium at near-weapons-grade levels.
Israel launched its campaign against Iran on February 28, alongside the United States, to degrade the Iranian regime’s military capabilities, distance threats posed by Iran — including its nuclear and ballistic missile programs — and “create the conditions” for the Iranian people to topple the regime, the military and other Israeli leaders have said.
The senior officer said that if, under the ongoing negotiations between the US and Iran, no agreement is reached to remove the uranium stockpile and halt enrichment in the country, the achievements of the 40 days of fighting will have been for nothing.
“If the nuclear objective is not achieved, then everything we did in Iran will be one big failure. The evil Iranian regime can pounce on the nuclear program,” the official said during a briefing for reporters, speaking on condition of anonymity.
The officer added that “if the uranium is removed from Iran through diplomatic means, we have done our part.” However, if that does not happen, Israel would need to launch another operation in Iran to achieve the objective.

During a recent visit to southern Lebanon, IDF Chief of Staff Lt. Gen. Eyal Zamir said that “every [goal] the political echelon defined for us regarding the current campaign in Iran and Lebanon has been achieved and even beyond that.”
“In doing so, we have created the operational conditions for the processes now being led by the political echelon,” he stated.
IDF’s hands ‘tied’ in Lebanon
The officials said the Israeli military is optimistic that a solution will be found to counter the fresh threat of Hezbollah’s first-person view (FPV) fiber-optic cable-guided drones, which have been repeatedly used in attacks on Israeli troops in southern Lebanon and northern Israel in recent weeks.

The military official said the IDF has been taking the threat seriously and working to develop and test systems to counter fiber-optic FPV drones, which are immune to electronic jamming. However, it is unlikely that any such system would be ready in the short term, he said, nor would it provide a hermetic solution to the threat.
“There is no magic solution. But we are optimistic that we will find a solution for the drones,” he said.
Still, the official said the most effective way to counter the threat would be to target the drone operators deep in Lebanon and Hezbollah’s supply chain for the drones.
However, this is currently not possible due to the ceasefire, as Israel is only permitted to target imminent threats to troops in southern Lebanon, such as drone operators actively piloting a drone.
“We need to go on the offense,” the officer said, while noting that currently, “our hands are tied.”

The Israeli Air Force has been assisting ground troops in Lebanon in dealing with the FPV drone threat by deploying mobile radars to detect them and alert forces, who can then attempt to shoot them down.
The IAF has also carried out interceptions, reporting that it shot down at least 27 FPV drones using the short-range Iron Dome air defense system.
While the military has deployed the Iron Beam — a high-powered laser system designed to shoot down drones and other aerial threats at a far lower cost per interception — it has seen limited use and has not yet been declared operational within the IDF. The senior officer said the Iron Beam’s coverage is partial, and more time is needed for a wider and more complete laser-based defense array.

Iran is using the ceasefire to dig up the missiles and other munitions stored underground or buried in US and Israeli strikes, a US official and two others familiar with the matter told NBC News.
According to NBC, the US believes that Iran is aiming to “quickly reconstitute” its capabilities to enable it to attack targets across the Middle East if fighting resumes.
One of the US officials added that US President Donald Trump is likely to decide on his next steps within the coming days.
Earlier this week, Trump admitted that Iran still has missiles and drones. US Secretary of State Marco Rubio told Fox News that Iran has “half the missiles” it had prior to the war, but “none of the factories.”
Last month, US Secretary of War Pete Hegseth said in a Pentagon briefing that Iran, “can dig out for now, but you can’t reconstitute, but we can.”
Asked by NBC for comment, a spokesperson for the Defense Department pointed to Hegseth’s remarks.
