Europe's largest nuclear power plant was forced to use emergency diesel generators for several hours on Wednesday to run cooling systems for the second time in less than a week after shelling in Ukraine cut electricity supplies.
Since Russia invaded Ukraine and took control of the plant, the war around the six-reactor station has raised fears of a catastrophe just 500 km (300 miles) from the site of the world's worst nuclear accident, the 1986 Chernobyl disaster.
