In a statement on X, the agency said Director General Rafael Grossi had “reiterated the crucial importance” of holding talks with Iranian authorities to resume the IAEA’s “indispensable” monitoring and verification work “as soon as possible.”
The inspectors had remained in Tehran throughout the 12-day conflict between Iran and Israel.
The announcement follows a report by the Wall Street Journal that the inspectors were pulled out over safety concerns and transported by road to Armenia in a departure coordinated with Iranian authorities.
Citing sources familiar with the matter, the newspaper reported that the agency had been trying to arrange the exit for several days and chose ground transport to reduce visibility and risk.
The move comes after weeks of rising tensions between Tehran and the UN nuclear watchdog. On Wednesday, Iranian President Masoud Pezeshkian enacted a law requiring the suspension of cooperation under the Nuclear Non-Proliferation Treaty’s safeguards agreement unless Iran’s demands for security guarantees are met.
Tehran has accused the IAEA of sharing sensitive data with Israel and the US, and of failing to condemn last month’s airstrikes on Iranian nuclear sites.
While Iran has denied ending cooperation entirely, Foreign Minister Abbas Araghchi said coordination with the agency would now be managed through Iran’s Supreme National Security Council.
This is while hardline Iranian media have called for Grossi's arrest and execution, and a senior judiciary official said Grossi could face trial in absentia for “deceptive actions.”
It remains unclear when or whether IAEA inspectors will return. WSJ reporter Laurence Norman said there is “no reason to feel confident” they will be back in Tehran anytime soon, adding that it could be years before monitoring operations resume.
