IAEA chief: No information on Iran’s nuclear materials or facilities

International Atomic Energy Agency Director General Rafael Grossi said on Monday that the agency has not received any recent information from Iran regarding the status of its declared nuclear materials and facilities, and has been unable to access them for on-site verification.

Grossi explained, during his address to the IAEA Board of Governors in Vienna, that this situation has prevented the agency from fulfilling its safeguards responsibilities at Iran’s declared nuclear sites and from verifying the status of related nuclear materials.

The IAEA chief noted that for over a year, the agency has lost “continuity of knowledge” regarding Iran’s declared stocks of low-enriched uranium and uranium enriched up to 60% U-235 at facilities affected by military attacks in June 2025.

Grossi described the lack of information and inability to verify as “a serious proliferation concern,” calling for the situation to be addressed with the utmost urgency.

He added that the absence of access and information has prevented the agency from assessing Iran’s implementation of relevant Security Council resolutions and Board of Governors decisions issued in November last year and June this year. He urged Iran to cooperate “constructively” with the agency to enable the full and effective implementation of safeguards under the Nuclear Non-Proliferation Treaty.

Grossi stressed that “a return to diplomacy and negotiations” to resolve issues related to Iran’s nuclear program is essential, noting the agency’s readiness to support such efforts and warning of the implications of Iran’s nuclear program for the global non-proliferation regime.
