A huge nuclear power plant occupied by Russia during its invasion of Ukraine is "completely out of control", The head of the UN's nuclear agency says.
Rafael Grossi was quoted by the Associated Press news agency as saying the Zaporizhzhia plant needed an inspection and repairs.
"You have a catalogue of things that should never be happening in any nuclear facility," he said.
Europe's biggest nuclear plant is dangerously close to the fighting.
US Secretary of State Antony Blinken accused Russia earlier this week of using the plant, which it overran in March, as a military base to launch attacks on Ukrainian forces.
Ukrainian officials have said Russians station troops and store military hardware on the grounds of the power station on the Dnipro river in the south of Ukraine.
But a Russian-installed official in the region told Reuters news agency that Ukrainian forces were using Western-supplied weapons to attack the plant.
