VIENNA (AP) — 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 watchdog circulated to member states and seen Friday by The Associated Press.
The report from the International Atomic Energy Agency stressed that therefore it “cannot verify whether Iran has suspended all enrichment-related activities,” or the “size of Iran’s uranium stockpile at the affected nuclear facilities.”
The IAEA report on Friday warned that due to the continued lack of access to any of Iran’s four declared enrichment facilities, the agency “cannot provide any information on the current size, composition or whereabouts of the stockpile of enriched uranium in Iran.”
The report stressed that the “loss of continuity of knowledge over all previously declared nuclear material at affected facilities in Iran needs to be addressed with the utmost urgency.”
According to the IAEA, Iran maintains a stockpile of 440.9 kilograms (972 pounds) of uranium enriched up to 60% purity — a short, technical step away from weapons-grade levels of 90%.
That stockpile could allow Iran to build as many as 10 nuclear bombs, should it decide to weaponize its program, IAEA director general Rafael Grossi warned in a recent interview with the AP. He added that it doesn’t mean that Iran has such a weapon.
Such highly enriched nuclear material should normally be verified every month, according to the IAEA’s guidelines.
Iran long has insisted its program is peaceful, but the IAEA and Western nations say Tehran had an organized nuclear weapons program up until 2003.
The IAEA also reported that it had observed, through the analysis of commercially available satellite imagery, “regular vehicular activity around the entrance to the tunnel complex at Isfahan.”
The facility in Isfahan, some 350 kilometers (215 miles) southeast of Tehran, was mainly known for producing the uranium gas that is fed into centrifuges to be spun and purified.
Israel has struck buildings at the Isfahan nuclear site, among them a uranium conversion facility. The U.S. also struck Isfahan with missiles during the war last June.
The IAEA also reported that through the analysis of commercially-available satellite imagery, it has observed “activities being conducted at some of the affected nuclear facilities, including the enrichment facilities at Natanz and Fordow,” but it added that “without access to these facilities it is not possible for the Agency to confirm the nature and the purpose of the activities.”
The confidential IAEA report also said Friday that Iran did provide access to IAEA inspectors “to each of the unaffected nuclear facilities at least once since the military attacks of June 2025, with the exception of Karun Nuclear Power Plan, which is in the early stages of construction and does not contain nuclear material.”
