International Atomic Energy Agency Director General Rafael Grossi has claimed that most of Iran’s enriched uranium is likely still at the Isfahan nuclear complex, which was targeted in airstrikes last year.
In an interview with The Associated Press, Grossi added that the International Atomic Energy Agency has satellite images showing the effects of recent airstrikes by the United States and Israel against Iran, noting that “information is still coming in.”
The agency’s inspections in Isfahan were halted when Israel launched a 12-day war in June 2015, in which the United States bombed three Iranian nuclear sites.
According to Grossi, the UN nuclear watchdog believes that a large portion of Iran’s highly enriched uranium “was stored there in June 2025 when the war began, and has been there ever since.”
Satellite images taken by Airbus showed a truck loaded with 18 blue containers entering a tunnel at the Isfahan Nuclear Technology Center on June 9, 2025, just before the war began.
According to the agency, Iran has 440.9 kilograms of uranium enriched to 60 percent, a short technical step that separates it from the 90 percent enrichment level used in nuclear weapons.
Grossi indicated that the agency believes that about 200 kilograms of that amount was stored in tunnels at the Isfahan site.
