The International Atomic Energy Agency (IAEA) has been unable to inspect Iranian nuclear facilities since the US and Israel launched attacks on the sites in June 2025, according to a confidential report circulated to UN member states and seen by The Associated Press (AP) news agency.
The IAEA said it “cannot provide any information on the current size, composition or whereabouts of the stockpile of enriched uranium in Iran or whether Iran has suspended all enrichment-related activities”.
The organisation also warned it was “unable to discharge its safeguards responsibilities” in Iran under the Nuclear Non-Proliferation Treaty, calling it “indispensable and urgent” for Tehran to meet its obligations.
The only Iranian facility inspected since a previous report in February has been the Bushehr nuclear power plant, visited on June 1 to 3, according to the AP.
The IAEA’s last recorded figure shows Iran holding 440.9kg (972lb) of uranium enriched to 60 percent purity, a short technical step from weapons-grade levels.
IAEA Director General Rafael Grossi reiterated in the report his full support of the negotiations under way between Washington and Tehran, “aimed at finding a mutually acceptable solution to issues related to Iran’s nuclear programme, and his readiness … to support an eventual agreement”.
