The U.N. nuclear watchdog’s governing board voted Wednesday to report Iran to the Security Council over unresolved questions involving uranium particles found at undeclared locations and Tehran’s failure to satisfy its nuclear safeguards obligations.

The International Atomic Energy Agency’s Board of Governors voted Wednesday to report Iran to the U.N. Security Council for the first time in 20 years, escalating a years-long dispute over Tehran’s cooperation with inspectors investigating undeclared nuclear material.

The resolution passed with support from 23 of the IAEA board’s 35 members, according to The Associated Press.

China, Russia and Niger voted against the measure, while eight countries abstained. One member did not vote because it was in arrears, diplomats told the AP on condition of anonymity because Wednesday’s proceedings were held behind closed doors.

The United States, Britain, France and Germany sponsored the resolution.

At the center of the dispute are uranium particles detected by IAEA inspectors at locations Iran had not declared as nuclear sites. The agency has repeatedly said Tehran has failed to provide technically credible explanations for the material or sufficient information about where related nuclear material or contaminated equipment may now be located.

Those unresolved questions have prevented the agency from providing assurance that Iran’s nuclear program is exclusively peaceful.

The board formally found Iran in noncompliance with its nuclear safeguards obligations in June 2025 after years of unsuccessful attempts to obtain satisfactory answers from Tehran.

Western governments have said the evidence could shed additional light on undeclared nuclear activities associated with an Iranian weapons program they suspect existed until 2003. Iran has consistently denied seeking nuclear weapons and maintains that its nuclear activities are peaceful.

Wednesday’s action does not itself impose new U.N. sanctions or determine that Iran possesses a nuclear weapon. It formally places the safeguards dispute before the Security Council, where members can consider further diplomatic action.

The referral represents the most significant IAEA escalation involving Iran since the agency last reported the country to the Security Council two decades ago.

Iran has rejected the latest action as politically motivated, while the countries supporting the resolution argue that the dispute stems from Tehran’s continuing obligation under its safeguards agreement to account for nuclear material and provide inspectors with the information and access necessary to verify its declarations.

With the 23-3 vote, the unresolved investigation has now moved beyond the IAEA board and back before the U.N. Security Council, significantly raising the diplomatic stakes surrounding Iran’s nuclear program.
