The International Atomic Energy Agency’s Board of Governors has voted to refer Iran to the United Nations Security Council over its failure to comply with nuclear safeguards obligations, marking the first such referral in two decades.
The resolution was approved on Wednesday, September 9, 2026, with 23 of the IAEA’s 35 board members voting in favour. China, Russia and Niger opposed the measure, while eight countries abstained and one did not vote.
The move follows prolonged concerns over Iran’s nuclear activities and its failure to provide the IAEA with sufficient access and information needed to verify its nuclear materials and facilities.
The agency has particularly raised concerns over uranium traces discovered at previously undeclared sites and the lack of access to some nuclear facilities following attacks on Iran’s nuclear infrastructure.
The referral represents a significant escalation in international pressure on Tehran. The last time the IAEA Board took a similar step involving Iran was two decades ago, leading to years of United Nations Security Council action over the country’s nuclear programme.
Iran has rejected the resolution, describing it as politically motivated and arguing that circumstances surrounding recent military attacks on its nuclear facilities have made inspections difficult. Tehran maintains that its nuclear programme is peaceful.
The IAEA has estimated that Iran had about 440.9 kilogrammes of uranium enriched to 60 per cent before the recent attacks. While that material is below the roughly 90 per cent enrichment level generally associated with weapons-grade uranium, the quantity has intensified international concerns over the potential proliferation risks.
The referral now places Iran’s nuclear dispute back before the UN Security Council, although any further action could face resistance from Russia and China, which have opposed the latest IAEA measure.
