International Atomic Energy Agency Director General Rafael Grossi said the agency has been unable to verify the status and location of Iran’s stockpile of highly enriched uranium since military strikes by the United States and Israel hit several nuclear sites in June.
The IAEA said it has not been granted access to Iran’s four declared enrichment facilities and has therefore lost “continuity of knowledge” over previously declared nuclear material at affected sites. As a result, it cannot verify whether Iran has suspended all enrichment-related activities or confirm the current size, composition or whereabouts of its enriched uranium stockpile.
Grossi said his agency “will not be in a position to provide assurance that Iran’s nuclear program is exclusively peaceful” until Iran improves its cooperation.
Inspectors have observed regular vehicular activity at bombed sites, including the underground complex at Isfahan and the enrichment facilities at Natanz and Fordow, through satellite imagery. However, Grossi said that without on-site inspections the agency cannot determine the nature or purpose of those activities.
According to the IAEA, Iran holds 440.9 kg (972 pounds) of uranium enriched up to 60% purity, a short technical step from weapons-grade levels of 90%. Grossi has previously said that while such material does not mean Iran has a nuclear weapon, it could, in theory, be sufficient for multiple bombs if further enriched.
The warning comes as Iran and the United States continue indirect talks over Tehran’s nuclear activities. Iran maintains that its nuclear program is exclusively peaceful.
