Background
Pripyat was evacuated in 1986 following the explosion and fire at Chernobyl, the world's worst nuclear disaster.
More than 30 people died in the immediate aftermath of the explosion, which tore through Chernobyl's No. 4 reactor on April 26, 1986.
In late February, during the first week of the war, Chernobyl plant and its surrounding territory fell into the hands of Russian troops.
