Ukrainian authorities say Russian warplanes have carried out new strikes on residential areas in eastern and central parts of the country.
Ukrainian officials said two people, including a seven-year-old child, were killed in the town of Chuhuiv just east of Kharkiv in eastern Ukraine late on Tuesday.
And in the city of Malyn, in the Zhytomyr region west of the capital Kyiv, at least five people, including two children, were killed in a Russian air strike.
The Russian artillery has pounded the outskirts of Kyiv, forcing civilians to hide in shelters while water, food and power supplies have been cut, said Yaroslav Moskalenko, an official who coordinates humanitarian efforts in the Kyiv region.
He said that the shelling made it impossible to evacuate the bodies of five people who died when their vehicle was fired upon in Borodianka near Kyiv and the bodies of 12 patients of a psychiatric hospital there.
He said another 200 patients were stuck there without food and medicine.
