Ukraine has accused Russian forces of bombarding civilian infrastructure in a revenge attack that caused widespread blackouts and left thousands without power.
Ukrainian President Volodymyr Zelensky said Russian missile strikes had targeted water facilities and a thermal power station in Kharkiv in the retaliatory attacks, which sparked mass blackouts.
It comes after Ukrainian troops forced Russia to abandon its main bastion in the Kharkiv region in a rapid weekend offensive.
Power outages filled the Kharkiv and Donetsk regions with darkness, meanwhile partial blackouts also occurred in the Zaporizhzhia, Dnipropetrovsk and Sumy regions.
“No military facilities, the goal is to deprive people of light and heat,” Mr Zelensky said on Twitter late on Sunday.
The US ambassador to Ukraine, Bridget Brink, echoed Mr Zelensky’s sentiments and condemned the strikes.
“Russia’s apparent response to Ukraine liberating cities and villages in the east: sending missiles to attempt to destroy critical civilian infrastructure,” she said on Twitter.
Moscow has denied its forces deliberately target civilians.
