Six people were killed after Russia destroyed a building in the eastern town of Toretsk in the early hours of Monday.
Rescuers recovered five dead bodies from the wreckage in the Donetsk region of Ukraine.
One person died in hospital and two people were saved, the State Emergency Service of Ukraine said.
It shared photos of the devastation on social media, writing: "Today, from the very morning, the town of Toretsk was shelled, as a result of a shell hit, a two-story building in which there were people was destroyed.
"During the search and rescue operations, the Rescue Service officers found and seized the bodies of five killed, rescued three people from the rubble, one of whom died in the hospital."
Toretsk, which has a population of around 30,000, lies 30 miles south of Kramatorsk, one of the last Ukrainian-controlled towns in the industrial east.
Russian forces are working to capture the entire Donbas region and recently wrested control of the sister cities Lysychansk and Severodonetsk from Ukrainian troops.
