Air raid sirens sounded in Kyiv on Sunday night as the latest wave of drone and missile strikes from Russia continued.
An attack which began shortly before midnight targeted critical infrastructure, Kyiv regional governor Oleksiy Kuleba said.
One man in Kyiv was injured by debris from a destroyed Russian drone, the capital’s mayor said.
The attacks have continued for several days over the New Year period.
Meanwhile, the Ukrainian Armed Forces said 400 Russian soldiers had been killed in on New Year’s Eve in Makiivka, in the Russian-occupied Donetsk region.
In a rare move, pro-Russian authorities admitted to casualties. But Russia refused to confirm the number of deaths, and the BBC is unable to verify this.
It comes after Ukrainian president Volodymyr Zelensky wished for victory and a “return to normal” for Ukraine in 2023.
In a new year address on Russian TV, President Vladimir Putin said Russia would fight to protest its sovereignty and independence.
