IAEA Board Orders Iran to Declare 440.9 kg of Uranium, Allow Checks After 21-3 Vote
3 articles · Updated · Reuters · Jun 10
Summary
Twenty-one of the IAEA board’s 35 members backed a U.S.-led resolution ordering Iran to disclose its remaining enriched uranium and grant inspectors prompt access to verify it at bombed nuclear sites.
The demand centers on material believed to have survived Israeli and U.S. strikes last June, including 440.9 kg enriched to up to 60% purity—enough, if further enriched, for 10 nuclear weapons by IAEA yardsticks.
Russia, China and Niger opposed the measure while 10 countries abstained, and Tehran denounced it as an attempt to "whitewash" U.S. and Israeli attacks that halted inspections and forced IAEA staff out.
The vote lands as U.S.-Iran ceasefire and nuclear talks already look strained after the sides traded strikes and Trump accused Iran of delaying a deal, raising the risk that Tehran could again curb cooperation.

The Iran-IAEA Breakdown: 440kg of Near-Weapons-Grade Uranium and the New Middle East Nuclear Crisis
Overview
On June 10, 2026, the IAEA Board of Governors demanded that Iran declare and verify its enriched uranium stockpile, which stands at 440.9 kilograms of uranium enriched up to 60%—just a technical step from weapons-grade. Iran immediately rejected this resolution, deepening the crisis and highlighting international concerns about the transparency and peaceful intent of its nuclear program. Historically, Iran has responded to such demands by escalating its nuclear activities or reducing cooperation with the IAEA. Recent geopolitical tensions have further fueled Iran’s defiance, making the situation more volatile and challenging for global nonproliferation efforts.
