Russian forces at Ukraine's Zaporizhzhia nuclear power plant have likely undermined the security and safety of the plant's operations, the UK's defence ministry says.
Europe's largest nuclear plant has been under Russian control since March but is still operational.
The UK defence ministry says Russian troops are probably using the plant as a shield to deter Ukrainian attacks.
The UN nuclear watchdog has warned the plant is "completely out of control".
The nuclear plant lies in the south-east of Ukraine along the eastern bank of the Dnipro river. It is currently still being operated by Ukrainian employees, though Russia is occupying the plant and the region around it.
It consists of six pressurised water reactors and stores radioactive waste.
