Repeated shelling of the Zaporizhzhia nuclear power plant in southern Ukraine has raised the possibility of a grave accident just 500 km (300 miles) from the site of the world's worst nuclear accident, the 1986 Chernobyl disaster.
The International Atomic Energy Agency (IAEA), which has repeatedly expressed concerns over the shelling of the plant, has proposed the establishment of a nuclear safety and security protection zone around the plant.
