Ukrainian President Volodymyr Zelenskyy said that Russia would surely launch new missile attacks on his country, and warned defence forces and citizens to be prepared to withstand a new week of strain on the power grid.
Snow fell in Kyiv and temperatures hovered around freezing on Sunday with fog forecast overnight.
City authorities said workers were close to completing restoration of power, water and heat, but high consumption levels meant some blackouts had been imposed. Millions in and around Kyiv were coping with disruptions caused by waves of Russian air strikes.
"We understand that the terrorists are planning new strikes. We know this for a fact," Volodymyr Zelenskyy said in his nightly video address. "And as long as they have missiles, they, unfortunately, will not calm down."
