Ukrainian forces kept pushing north in the Kharkiv region and advancing to its south and east, Ukraine's army chief said on Sunday, a day after their rapid surge forward drove Russia to abandon its main bastion in the area, Reuters reports.
Ukrainian officials accused retreating Russian forces of launching retaliatory attacks on civilian infrastructure, including a thermal power station in Kharkiv, that the authorities in Kyiv said caused widespread blackouts.
"No military facilities, the goal is to deprive people of light & heat," Ukrainian President Volodymyr Zelenskiy wrote on Twitter of the attacks.
Moscow denies its forces deliberately target civilians.
