Following the June 2025 strikes on Iranian nuclear facilities and additional attacks in early 2026, the IAEA lost physical access to the enrichment sites at Isfahan, Fordow, and Natanz, halting verification activities under Iran's NPT safeguards agreement. A June 2026 US-Iran memorandum of understanding explicitly references IAEA supervision of nuclear material and facilities, prompting Director General Rafael Grossi to state that inspections will occur and that modalities are under discussion with Tehran. Iranian officials, however, have conditioned any return to the damaged sites on completion of a final agreement and sanctions relief, with no confirmed visits reported since the conflict. Satellite imagery continues to show activity at storage tunnels, particularly at Isfahan, while ongoing US-Iran talks and potential diplomatic timelines remain the main variables that could enable or delay IAEA entry to these locations.
