Officials in Ukraine have accused Russia-backed separatists of firing on the settlement of Zaitseve, in a government-controlled part of the Donbas region.
Ukrainian military officials said on August 20 that the settlement came under fire late on August 19. Incendiary weapons caused fires that destroyed several homes and other property.
No injuries were reported.
Ukrainian forces did not return fire because of a cease-fire that is in place, officials said.
According to the United Nations, nearly 10,000 people, including 2,700 civilians, have been killed in the conflict since early 2014.
Nearly 24,000 people have been injured and more than 1 million people have been displaced.
