Iran has not allowed the United Nations nuclear watchdog to access nuclear facilities affected by the 12-day war in June, according to a confidential report by the (IAEA), circulated to member states and accessed on Friday (February 27, 2026.

Iran stored highly enriched uranium at underground site: IAEA report

Some of ​Iran’s most highly enriched ‌uranium, close to ​weapons grade, ⁠was stored in an underground area of ‌its nuclear site in Isfahan, ‌the IAEA said in its report.

It is the first time the ‌agency has reported where uranium ⁠enriched to up to 60% ‌purity, close to the 90% of weapons grade, has been stored.

The tunnel complex’s ‌entrance was hit ​in U.S. and Israeli military ⁠strikes in June but the ⁠facility seems largely unharmed, ‌diplomats say.
