Vladimir Putin struck back at Ukraine overnight with devastating missile hits on the Ukrainian power grid plunging millions into darkness as Russian troops flee.
The blitz was in revenge for the military humiliation Russian forces have suffered in Kharkiv region where his troops are in retreat.
Ukraine President Volodymyr Zelensky said the strikes aimed to "deprive people of light and heat" and he accused Putin of "terrorist acts" which hit civilian, not military targets.
