# Iran-IAEA nuclear dispute and confirmed Syrian reactor > Live situation record from CLSTR: https://clstr.news/situations/iran-iaea-nuclear-inspection-dispute > Updated: 2026-09-10T16:26:07.000Z. Sources: 48. Developments: 4. The standoff between Iran and the International Atomic Energy Agency (IAEA) has intensified as the agency warns of significant proliferation risks. The IAEA reported a loss of ‘continuity of knowledge’ regarding previously declared inventories of low-enriched and highly enriched uranium, stating that the inability to verify nuclear material is a ‘matter of proliferation concern.’ This verification gap persists because inspectors have been denied access to several sites, including the Isfahan plant, since military strikes by the United States and Israel in June 2025. Mohammad Eslami, head of Iran’s Atomic Energy Organization, continues to maintain that inspections of sites targeted by military action cannot occur until specific protocols and criteria are developed and approved. Recent IAEA reporting indicates that, with the exception of the Bushehr power plant, no verification activities have been performed at any declared sites since February. The agency has lost the ability to track declared nuclear inventories at facilities targeted in military strikes, noting that satellite imagery shows damage to the heavy water facility in Khandab following an attack on March 27. Furthermore, the IAEA observed regular vehicle activity at a tunnel entrance in Isfahan used to store 60 percent enriched uranium, though the agency remains uncertain regarding the exact location and legal status of the Isfahan fuel enrichment facilities. Prior to the strikes, the IAEA reported that Iran possessed approximately 440.9 kilograms of uranium enriched to 60 percent purity. In Syria, following the removal of the Assad regime, new authorities granted inspectors access to suspected sites. The IAEA concluded that the former government operated an undeclared nuclear program in violation of its safeguards agreement. In Deir ez-Zor, inspectors discovered cooling infrastructure consistent with a nuclear reactor, a fuel fabrication facility, and locations for nuclear fuel and waste storage. ## Claims - The former Syrian authorities failed to report nuclear material, facilities, and activities. (corroborated by 16 sources) - The IAEA confirmed that cooling infrastructure uncovered at a Syrian site is consistent with a nuclear reactor. (corroborated by 15 sources) - The IAEA identified a fuel fabrication plant and a storage location for nuclear fuel and waste in Syria. (corroborated by 14 sources) - IAEA inspectors secured 73 tonnes of natural uranium metal in Syria, including 55 tonnes of fuel rods. (corroborated by 10 sources) - Iran is refusing to cooperate with IAEA inspectors and has not provided information on approximately 440 kilograms of nearly weapons-grade uranium. (corroborated by 5 sources) - Military attacks by Israel and the United States against Iranian nuclear facilities have created an unprecedented situation. (corroborated by 5 sources) - IAEA inspectors currently lack access to more than 20 Iranian nuclear program sites. (corroborated by 4 sources) - The IAEA cannot verify if Iran has suspended uranium enrichment or reprocessing activities. (corroborated by 4 sources) - Syria has begun destroying remnants of a clandestine Assad-era chemical weapons program.

Meanwhile, verification of Iran's nuclear program remains stalled. 33 sources. https://clstr.news/cluster/iran-refuses-iaea-cooperation-on-nuclear-program ### 2026-08-26: Iran: IAEA cannot inspect attacked nuclear facilities without new protocols Iran's nuclear chief Mohammad Eslami says the IAEA cannot inspect attacked nuclear facilities until new security protocols are approved, citing pressure from the US and Israel. 9 sources. https://clstr.news/cluster/iran-demands-new-iaea-protocols-for-inspecting-attacked-nuclear-facilities --- Cite as: Iran-IAEA nuclear dispute and confirmed Syrian reactor.
