Ukraine said it had shot down all 24 drones sent overnight by Russia, including 15 around the capital, and 47 of 55 Russian missiles - some fired from Tu-95 strategic bombers in the Russian Arctic.
Eleven people were killed and 11 wounded in the drone and missile strikes, which spanned 11 regions and also damaged 35 buildings, a State Emergency Service spokesperson said.
Prime Minister Denys Shmyhal said electricity substations had been hit as Russia continued to target energy facilities.
