IAEA Has Been Unable to Monitor Iran's Nuclear Sites Since June 2025 Strikes

In depth

Iran announced a uranium enrichment facility in Isfahan on the eve of the strikes carried out by Israel and the United States in June 2025. Since the strikes, Iran has not allowed International Atomic Energy Agency inspectors to visit the facility.

The International Atomic Energy Agency said it has no access to Iran's nuclear facilities and no information on their condition. The agency does not know the exact location of the enrichment facility in Isfahan or whether it contains nuclear material.

A confidential agency report states that a large amount of uranium enriched to military level is hidden in the underground tunnel complex in Isfahan. The agency warns of a serious risk of nuclear proliferation.
