IAEA's Grossi calls for 'military restraint' after Israel strikes two Iranian nuclear facilities

The International Atomic Energy Agency (IAEA) issued a statement on 27 March 2026 after Israel struck two Iranian nuclear facilities: 'IAEA Director General Rafael Grossi reiterates his call for military restraint to avoid any risk of a nuclear accident.' The IAEA also reported 'no increase in off-site radiation levels' at the Shahid Rezayee Nejad Yellowcake Production Facility (the Ardakan yellowcake plant). The IAEA is the UN's nuclear watchdog and has inspectors with access to Iranian nuclear sites under the NPT and related agreements. Grossi's 'military restraint' call — addressed to both Israel and the US — comes after the most intensive day of nuclear-adjacent strikes in the conflict: the Arak IR-40 heavy water reactor (2nd strike, potentially ending plutonium production capacity) and Ardakan (Iran's sole yellowcake plant). The IAEA's confirmation of no radiation release at Ardakan corroborates the AEOI's initial assessment.
