The majority of Iran’s highly enriched uranium is likely still at its Isfahan nuclear complex, which was bombarded by air strikes last year and faced less intense attacks in this year’s US-Israeli war, the head of the UN nuclear agency has told The Associated Press, Turkish outlet TRT World reports.

International Atomic Energy Agency (IAEA) Director General Rafael Grossi has said in an interview that the watchdog has satellite images showing the effects of the latest US-Israeli air strikes against Iran and that “we continue to get information”.

The UN nuclear watchdog believes a large percentage of Iran’s highly enriched uranium “was stored there in June 2025 when the 12-day war broke out, and it has been there ever since”, Grossi said.

“We haven’t been able to inspect or to reject that the material is there and that the seals — the IAEA seals — remain there,” he says. “I hope we’ll be able to do that, so what I tell you is our best estimate.”
