STORY: Video released by Donetsk region police showed rescuers helping a man in the remains of a damaged building.

Reuters was not able to independently verify the date it was filmed and the location of the footage.

The invincibility point that was hit overnight in the city of Kostiantynivka in the eastern Donetsk region was one of many such shelters created by authorities across Ukraine to provide access to electricity, heating, water and other basic services.

Four other civilians were also killed during the night, local officials said. The dead included two people killed in heavy Russian shelling of the Sumy region on northern Ukraine, President Volodymyr Zelenskiy's office said.
