Pictures have emerged of inside the Chernobyl nuclear power plant that was seized by Russian soldiers, with fears more than 100 Ukrainian guards may have been taken hostage.
The Ukrainian state nuclear company said at the end of March that Vladimir Putin's troops had left the defunct plant, which they had captured on the first day of the invasion.
More than 100 workers and 169 Ukrainian guards were trapped inside an underground nuclear bunker for more than a month without fresh air and natural light.
