IAEA board passes resolution reporting Iran to UN Security Council

While the Security Council is unlikely to take concrete action against ​Iran since its allies Russia and China are permanent, veto-wielding members, the move is an escalation in a diplomatic standoff between Iran ​and Western powers. Iran warned on Monday it would retaliate if the resolution passed.

Iran, Russia, China oppose Western nuclear push. Iran, Russia and China have rejected the draft resolution, saying the move has no legal basis. The three countries said the draft resolution “ignores attacks on Iran's nuclear facilities” and was “aimed at increasing pressure on Tehran and weakening Iran-IAEA cooperation”.

They also said any attempt to activate the “snapback” mechanism after the expiry of UN Security Council Resolution 2231 “has no legal effect”. China, Iran, and Russia, in a joint statement to the#IAEABoG today, condemned repeated attacks against Iran’s nuclear facilities under IAEA safeguards, together with continuing threats of further aggression.

Iran, Russia and China urged IAEA member states not to support the Western-drafted resolution.

The three countries’ opposition comes as Western powers seek to increase pressure on Tehran through international institutions over its nuclear programme. Iran says US is ‘delusional’An initial reaction by Iran's ⁠mission to the International Atomic Energy Agency, however, did not mention retaliation.

"Once again, a political resolution on Iran is nonconsensually adopted by the #IAEA BoG (Board of ​Governors)," it said on X, referring to the fact the resolution was voted on rather than adopted without any country objecting.بار دیگر، یک قطعنامه‌ غیراجماعی سیاسی در مورد ایران در شورای حکام آژانس بین‌المللی انرژی اتمی تصویب شد. این امر از یک الگوی آشنا تبعیت می‌کند و باعث فرسایش بیشتر و تسریع در فروپاشی کامل رژیم اشاعه سلاح‌های هسته‌ای می‌شود.وضعیت فعلی صرفاً به دلیل اقدامات تجاوزکارانه و جنایتکارانه…— Iran Mission UN Vienna (@PMIRAN_Vienna)September 9, 2026While the finding of non-compliance predates the war between the United States and Iran and concerns Tehran's failure to explain uranium traces found at undeclared sites that the agency spent years investigating, there is nowanother standoffover IAEA access to the sites bombed by Israel and the USLack of access ‘serious proliferation concern’Iran has not let IAEA inspectors return to its bombed sites, including the three uranium-enrichment plants at the ​heart of its nuclear programme that ​were destroyed or badly damaged in ⁠the military strikes.

Tehran has also not accounted for its stock of enriched uranium, some of which was enriched to up to 60% purity, a short step from the roughly 90% of weapons-grade.

"The Agency's lack of information ​about these facilities and associated nuclear material and our inability to conduct verification activities at these facilities is ​a matter of serious ⁠proliferation concern," IAEA chief Rafael Grossi 's board on Monday. "The situation needs to be rectified with the utmost urgency," he added.

The IAEA estimates Iran had 440.9 kg of uranium enriched to up to 60% before the US-Israeli attacks. That is enough, if enriched further, for 10 nuclear weapons, ⁠IAEA yardstick. ​How much has survived is unclear, although the IAEA has said it believes more than ​200 kg remains at one site.

Wednesday's resolution specifically mentioned two previous ones: the June 12, 2025 text finding Iran in non-compliance and the most recent one, from June of this year, ​telling Iran to declare its remaining enriched uranium stocks and let inspectors verify them.
