U.N. Nuclear Watchdog Demands Iran Provide ‘Complete Information’ on Enriched Uranium Stockpiles
IAEA board passes US-backed resolution as fears grow over nearly 1,000 pounds of material that could produce 10 nuclear bombs
VIENNA — The International Atomic Energy Agency’s (IAEA) Board of Governors has passed a resolution demanding that Iran provide “complete information” about its stockpile of near weapons‑grade nuclear material and grant inspectors immediate access to verify its location and status.
The measure, introduced by France, Germany, the United Kingdom, and the United States, was adopted on June 10 by a vote of 21 in favor, three against, with 10 abstentions at the IAEA’s headquarters in Vienna. Russia, China, and Niger opposed the resolution, while one member country did not participate in the vote.
The resolution stresses that providing the requested information and access is “essential and urgent” to enable the IAEA to verify that no nuclear material has been diverted for military purposes.
The Nuclear Shadow: What the IAEA Cannot See
Nearly one year after U.S. and Israeli strikes targeted Iran’s nuclear infrastructure, the IAEA remains unable to account for the country’s stockpile of uranium enriched to 60 percent purity — a short, technical step away from the 90 percent required for a nuclear weapon.
Prior to the June 2025 strikes, the IAEA had verified that Iran possessed 440.9 kilograms (972 pounds) of uranium enriched to 60 percent. According to IAEA Director General Rafael Grossi, this stockpile, if further refined, would be sufficient to produce as many as 10 nuclear bombs.
However, since the attacks — which heavily damaged Iran’s main enrichment facilities at Natanz, Fordow, and Isfahan — Tehran has denied IAEA inspectors access to the affected sites, citing safety concerns and the disruption of monitoring activities. The agency has also been unable to verify the status of the stockpile of near weapons‑grade uranium since the June 2025 bombing.
“The Agency cannot provide any information on the current size, composition or whereabouts of the stockpile of enriched uranium in Iran,” the IAEA stated in a confidential report circulated to member states in early June.
Adding to the complexity, Iranian authorities reportedly moved sensitive nuclear material in small, easily transportable containers, raising concerns that the stockpile may have been dispersed across multiple locations or buried in tunnel complexes.
Years of Non‑Compliance
The resolution “deeply regrets” Iran’s “failure to remedy” its non‑compliance with non‑proliferation obligations over the past 12 months. The IAEA board had found Iran officially in non‑compliance with its safeguards agreement for the first time in 20 years just before the June 2025 attacks.
A long‑running investigation into uranium traces detected at undeclared sites also remains unresolved. Since 2019, Iran has failed to provide the agency with “technically credible answers” regarding the origin and current location of this material. Western officials suspect the uranium traces could provide further evidence that Iran had a secret nuclear weapons program until 2003.
Tehran’s Defiant Response
Iran strongly rejected the resolution, calling it “counterproductive,” “politically motivated,” and “legally flawed”.
“This is a reversal of responsibility,” Iranian Deputy Foreign Minister Kazem Gharibabadi wrote on X, arguing that the resolution attempts to “whitewash military aggression and shift its costs onto the victim country”.
Iran’s ambassador to the UN in Vienna, Reza Najafi, warned that the measure could harm already‑fragile ceasefire talks between Tehran and Washington. “It further complicates the volatile situation, volatile ceasefire and the unfinished negotiations between Iran and the US,” Najafi told the AFP news agency.
The Iranian delegation cautioned the board to “exercise caution in its next steps” and indicated that Tehran could respond to what it considers politically motivated resolutions by expanding its uranium enrichment activities or narrowing its cooperation with the IAEA.
A Broader Escalation
The IAEA resolution came just hours after the United States and Iran exchanged military strikes across the Gulf region, the most significant escalation since a fragile ceasefire brokered by Pakistan took effect in early April.
The escalating attacks have threatened to derail efforts to end the war, as President Donald Trump warned that Tehran would “pay the price” for stalled peace negotiations. Despite the military tensions, Washington and Tehran continue indirect talks aimed at extending the ceasefire and eventually addressing the nuclear program.
What Comes Next
The IAEA board stated that it “will stand ready to take further action,” including by addressing the “timing and content” of a formal non‑compliance report for consideration by the UN Security Council.
Whether the new resolution will pressure Iran to comply or instead push Tehran further away remains to be seen. For now, the whereabouts of hundreds of kilograms of near weapons‑grade uranium remain unknown, and the IAEA’s ability to verify the peaceful nature of Iran’s program remains crippled.
Frequently Asked Questions (FAQs)
Q1: How much highly enriched uranium does Iran have?
A: According to IAEA estimates, Iran possesses 440.9 kilograms (972 pounds) of uranium enriched to 60 percent purity — a level just one technical step away from weapons‑grade. This material, if further refined, could be sufficient to produce as many as 10 nuclear bombs.
Q2: Why can’t the IAEA monitor Iran’s nuclear stockpile?
A: Since the U.S. and Israeli strikes in June 2025, Iran has denied IAEA inspectors access to the nuclear sites that were affected by the attacks. The agency has been unable to verify the size, location, or composition of the enriched uranium stockpile for nearly a year.
Q3: What does the new IAEA resolution demand?
A: The resolution demands that Iran provide “complete information” on its nuclear material inventories and grant IAEA inspectors immediate access to verify that information. It also “deeply regrets” Iran’s continued non‑compliance with its non‑proliferation obligations.
Q4: How did the vote go?
A: The resolution was passed with 21 votes in favor, three against (Russia, China, and Niger), with 10 abstentions. One member country did not vote.
Q5: How has Iran responded?
A: Iran rejected the resolution as “politically motivated” and “legally flawed.” Officials warned that the measure could complicate ongoing ceasefire talks with the U.S. and suggested that Tehran could respond by expanding its uranium enrichment activities.
Q6: What is the status of the U.S.-Iran ceasefire?
A: A fragile ceasefire brokered by Pakistan has been in place since early April, but it has been strained by recent military exchanges. The U.S. and Iran continue indirect talks aimed at extending the ceasefire and eventually addressing the nuclear program.
