More than 1 million energy consumers across Ukraine were without power after overnight Russian air strikes on energy facilities, a top presidential official said on Friday.

The strikes had affected around 700,000 residents in the eastern Kharkiv region, at least 200,000 each in the southern Odesa and southeastern Dnipropetrovsk regions and another 110,000 in the central Poltava region, said Oleksiy Kuleba, deputy head of the presidential administration.
