IAEA Refers Iran to UN Security Council Over Nuclear Non-Compliance

The Board of Governors of the International Atomic Energy Agency (IAEA) has passed a resolution accusing Iran of failing to adhere to its nuclear non-proliferation commitments, formally referring the matter to the United Nations Security Council (UNSC). This diplomatic action, supported by the United States and major European powers, occurs more than six months into the US-Israeli war against Iran and coincides with heightened tensions in the Strait of Hormuz.

The resolution expresses “grave concern” regarding Iran’s “continued noncompliance” with its obligations under the Nuclear Non-Proliferation Treaty (NPT). As a signatory, Iran is prohibited from developing nuclear weapons and must allow IAEA safeguards to verify that its nuclear material is used exclusively for peaceful purposes. However, the IAEA has been unable to access key Iranian nuclear facilities since the start of the 12-day war launched by the US and Israel in June 2025, which targeted sites such as Fordow, Natanz, and Isfahan.

In its latest statement, the IAEA board highlighted the lack of information about previously declared nuclear material and the inability to verify it as a critical “proliferation concern.” The agency called on Tehran to engage in unconditional talks to rebuild international confidence in the peaceful nature of its nuclear program. This marks the first time in two decades that the IAEA board has issued such a resolution.

Iran has condemned the move, describing it as baseless and driven by political pressure from Washington and its allies. Reza Najafi, Iran’s representative to the UN in Vienna, stated that the country has not suspended its safeguards obligations but cannot provide inspectors safe access due to ongoing military operations. He accused the US of disrupting verification processes and then using that disruption as a pretext for the resolution.

The referral now moves to the UN Security Council, though significant action is considered unlikely. Russia and China, both veto-holding members, are expected to block any further measures. Ali Vaez of the International Crisis Group described the resolution as an “exercise in futility,” noting that Western pressure would likely hit a wall at the Council.

The IAEA referral provides the US with additional justification for its military campaign. President Donald Trump has renewed threats to strike Pickaxe Mountain, an underground complex near the damaged Natanz facility, citing observed activity and warnings against Iranian deception. Trump has repeatedly claimed Iran is pursuing nuclear weapons, a assertion contradicted by IAEA findings and US intelligence agencies.

The current crisis follows a history of IAEA scrutiny dating back to the early 2000s. After Iran agreed to the 2015 Joint Comprehensive Plan of Action (JCPOA), it curbed its nuclear program and allowed extensive inspections. However, relations deteriorated after the US withdrew from the deal in 2018 under Trump, leading Iran to resume enrichment activities. In June 2025, the IAEA previously declared Iran non-compliant with safeguards, a report Tehran rejected as a precursor to military attacks.

IAEA Director General Rafael Grossi has not supported claims that Iran possesses the capability to build an atomic bomb, stating there is no proof of a systematic effort toward weaponization. The agency suspects Iran currently holds approximately 400kg of highly enriched uranium, enough to potentially manufacture ten nuclear weapons if further enriched.
