UN nuclear watchdog has lost all knowledge of Iran’s nuclear program: UN political chief
NEW YORK: The International Atomic Energy Agency lost continuity of knowledge across all of Iran’s declared nuclear facilities following US and Israeli strikes that began Feb. 28, 2026, which “could not be restored,” a senior UN official told the Security Council on Friday.
Rosemary DiCarlo, UN under-secretary-general for political and peacebuilding affairs, said the loss extended to the production and current inventory of centrifuges, rotors and bellows, heavy water, and uranium ore concentrate, citing the secretary-general’s most recent report on resolution 2231. It was adopted in 2015 and unanimously endorsed the Joint Comprehensive Plan of Action nuclear deal, providing sanctions relief in exchange for curbs on Iran's nuclear program.
The IAEA also reported “a significant deterioration in its situational awareness following the attacks against Iran by the United States and Israel,” DiCarlo said, briefing the council on non-proliferation issues under resolution 2231.
The IAEA had not conducted any in-field verification activities under Iran’s Nuclear Non-Proliferation Treaty Safeguards Agreement, the same instrument that had allowed it to monitor Tehran’s commitments under the JCPOA, DiCarlo said.
