The IAEA board of governors voted on Tuesday to refer Iran to the UN Security Council, citing a lack of information on Iran's nuclear material, including its stockpile of highly enriched uranium, and the denial of access to nuclear facilities for IAEA inspectors.
The resolution, tabled by the United Kingdom, France, Germany and the United States, was backed by 23 countries. Eight countries abstained, while China, Russia and Niger voted against.
Tehran condemned the decision. Iranian Deputy Foreign Minister Kazem Gharibabadi wrote on X that the IAEA had used the disruption caused by strikes on Iran's nuclear facilities as a pretext for the resolution. "They attack Iran's safeguarded nuclear facilities, disrupt the normal process of verification, and then use that very disruption as a pretext to issue a resolution," he said.
The IAEA has been unable to access Iran's nuclear facilities since Israel and the US carried out a series of strikes on those sites during a 12-day conflict in June 2025. The facilities were targeted again in a war launched by Israel and the US on 28 February.
Despite the referral, new sanctions are considered unlikely because Iran's allies China and Russia hold veto power in the Security Council. The resolution asks IAEA chief Rafael Grossi to report Iran to the council, setting the stage for a diplomatic confrontation with limited prospects for punitive action.
