Russian forces launched 36 rockets in a "massive attack" on Ukraine, most of which were shot down, Ukrainian President Volodymyr Zelenskyy said on Saturday.

More than a million households in Ukraine were left without electricity following Russian strikes on energy facilities across the country, the deputy head of the Ukrainian presidency, Kyrylo Tymoshenko, said Saturday.

The Russian side has not responded to the claims.
