The International Atomic Energy Agency has voiced “increasing concern” about an Iranian nuclear facility its inspectors have not been allowed to visit, saying in its latest report that it does not know the site’s exact location or whether it contains nuclear material.
Iran informed the agency on 12 June 2025 of plans to build a fuel enrichment plant in the city of Isfahan, a day before Israel began striking its nuclear sites, strikes the United States later joined that month.
In the report seen by news agencies, the IAEA said its “lack of information on Iran’s nuclear material and of access to facilities to verify it is a matter of serious proliferation concern and must be rectified with the utmost urgency”.
Since the latest war began, Tehran has restricted inspectors’ access to its sites, preventing verification of its enriched uranium stockpile, estimated before the June 2025 strikes at about 441 kilograms enriched to 60% purity, close to weapons grade.
The Isfahan complex was badly damaged in the strikes, especially its above-ground facilities, while the fate of its underground sites remains unclear. The agency believes much of Iran’s highly enriched uranium was stored there.
