A drone hit the Zaporizhzhia nuclear power plant in Russian-occupied southern Ukraine, the UN nuclear agency said, citing local officials.
The International Atomic Energy Agency (IAEA) posted on social media that the Russian-run plant's operator informed it that a drone had hit the turbine building on Saturday, "reportedly causing a hole in its wall".
Russian media carried a statement from state-owned nuclear power firm Rosatom accusing Ukraine of a deliberate attack — a claim strongly denied by Kyiv.
Close to the front line in southern Ukraine, Zaporizhzhia is the biggest nuclear power plant in Europe.
Moscow and Kyiv have repeatedly accused each other of risking a nuclear catastrophe with attacks since it was captured by Russia's forces in 2022.
