IAEA says it is increasingly concerned about Iran’s uninspected Isfahan enrichment plant
The International Atomic Energy Agency said it is increasingly concerned about Iran’s underground Isfahan Fuel Enrichment Plant, declared to the agency in June 2025, which Iran has not permitted inspectors to enter. A confidential report to member states, seen by Reuters, said the agency does not know the plant’s exact location, safeguards status or whether it contains nuclear material.

The IAEA had scheduled an inspection for June 13, 2025, but a bombing campaign began that day and prevented the visit. The report said Iran had also not permitted access to design plans, calling the information gap and lack of verification a serious proliferation concern requiring urgent correction.
Beyond Isfahan, the report urged Iran to disclose the status of its enrichment plants and account for highly enriched uranium, including material close to weapons-grade purity.
