A Kharkiv power substation, which Ukraine said was hit by a Russian missile strike on Sunday (September 11) evening and caused widespread blackouts, remained non-operational on Monday (September 12).
Reuters video of the substation showed a crater in the ground and the destroyed building where the master control room was located.
Ukrainian officials on Sunday accused retreating Russian forces of launching retaliatory attacks on civilian infrastructure, including the one on the thermal power station in Kharkiv.
Moscow denies its forces deliberately target civilians.
Kharkiv Mayor Ihor Terekhov described attacks on infrastructure as “cynical revenge” for the success of Ukrainian troops at the front, particularly in Kharkiv.
On Monday, Russian strikes again disrupted power and water supply in Kharkiv itself, killing at least one person, its mayor said.
