Russia has alleged that Ukraine targeted the Zaporizhzhia nuclear power station under Russian control, demanding a response from the West. However, Kyiv has denied involvement in the attacks. The International Atomic Energy Agency (IAEA) has long warned of risks at Zaporizhzhia, Europe's largest nuclear plant, and urged an end to the fighting. The plant, near the site of the Chornobyl disaster, has reactors in cold shutdown, except for one in "hot shutdown" for heating. The IAEA confirmed attacks on the plant but did not assign blame.
