The International Atomic Energy Agency (IAEA) Board of Governors adopted a resolution on June 10, 2026, calling on Iran to provide detailed information about its enriched uranium stockpiles and grant inspectors the access needed to verify those materials.

The 35-member board approved the resolution with 21 votes in favor, three against, and 10 abstentions. According to diplomats, Russia, China, and Niger voted against the measure.

The resolution urges Iran to provide the IAEA with “complete information on nuclear material inventories and design information for facilities” and to allow the agency immediate access required to verify that information.

The board expressed “grave concern” over findings by IAEA Director General Rafael Grossi, who reported that the agency has been unable for nearly a year to verify previously declared stocks of highly enriched uranium (HEU) and low-enriched uranium (LEU) in Iran.

It also stated that it “deeply regrets Iran’s continued failure to remedy its non-compliance over the past 12 months,” including its failure to provide the requested information and access needed for verification.

The resolution recalled a June 2025 decision by the board that found Iran had failed since 2019 to provide full and timely cooperation regarding undeclared nuclear material and activities at multiple undeclared locations.

Concerns Over Missing Uranium Stocks

The vote comes after Israeli and U.S. military strikes last year damaged or destroyed Iranian uranium enrichment facilities. While those attacks affected key nuclear sites, much of the enriched uranium produced before the strikes is believed to have survived.

The IAEA has said Iran has not informed the agency about the status or location of that material and has not allowed inspectors to return to the affected sites to verify its condition.

Before the military strikes, the agency estimated that Iran possessed approximately 440.9 kilograms of uranium enriched to up to 60% purity, a level that is technically close to weapons-grade material, although Iran maintains its nuclear program is intended for peaceful purposes.

Iran Criticizes Resolution

Iran strongly criticized the resolution, arguing that it overlooks the impact of the military attacks on its nuclear facilities.

Deputy Foreign Minister Kazem Gharibabadi said the strikes by Israel and the United States halted verification activities and forced IAEA inspectors to leave the country for safety reasons. He accused Washington of attempting to use the consequences of those attacks against Iran.

Today, Board of Governor adopted with a shaky vote, another political resolution on Iran’s peaceful nuclear activities; devoid of professionalism expected from a technical body.

Iran’s mission to the IAEA also warned the Board of Governors to be cautious in its approach, noting that previous resolutions have often been followed by reductions in Tehran’s cooperation with the agency or expansions of its nuclear activities.

Iran has described the latest measure as an attempt to “whitewash military aggression,” arguing that inspectors had access to its facilities before the attacks occurred.

Diplomatic Efforts Continue Despite Tensions

Despite the dispute, the resolution reaffirmed support for a diplomatic solution and called on Iran to engage seriously and without preconditions in negotiations aimed at building international confidence in the exclusively peaceful nature of its nuclear program.

The United States and Iran are continuing discussions focused on extending their ceasefire and opening broader negotiations on issues including Iran’s nuclear activities.

However, tensions remain high. U.S. President Donald Trump expressed frustration with the pace of negotiations, writing on social media that “Iran is all talk and no action” and warning that the country had taken too long to reach an agreement.

Trump has repeatedly stated that Iran must not be allowed to develop a nuclear weapon, while Iranian officials continue to insist that the country has no intention of doing so and that its nuclear program is for peaceful purposes.

The latest IAEA resolution adds further pressure on Tehran to cooperate with international inspectors while diplomatic efforts continue to address longstanding concerns over its nuclear activities.
