Russia has used more than 450 drones and 32 missiles in an overnight attack on Ukraine’s energy sector, Volodymyr Zelenskyy has said.
The president said there were power outages in nine regions - with about 600,000 households thought to have been cut off.
“It is precisely the civilian and energy infrastructure that is the main target of Russia’s strikes ahead of the heating season,” Mr Zelenskyy said on X.
Two million in Kyiv also temporarily lost water supply, Deputy Prime Minister Oleksii Kuleba wrote on Telegram.
