A Russian attack on the city of Kramatorsk in eastern Ukraine early Friday left two civilians dead, 13 others injured, and damaged dozens of homes, according to Ukrainian officials.

Pavlo Kyrylenko, the regional military leader in eastern Donetsk Province, confirmed the attack in social media posts and shared a video of the damage caused by 11 Russian rocket strikes. The video showed several homes that had sustained roof damage, and windows in some houses appeared to have been blown out. Law enforcement officials and rescuers were working in the area, Mr. Kyrylenko said.

“The Russians cynically and coldbloodedly turned the private sector of the city into ruins,” Mr. Kyrylenko said on social media posts.

The war in Ukraine is mainly being fought on two fronts. The eastern front has been focused on the provinces of Luhansk and Donetsk. Kramatorsk is in Donetsk Province and remains under Ukrainian control. Mr. Kyrylenko’s counterpart in Luhansk said that Ukrainian forces had repelled a Russian advance near settlements still under his forces’ control on Friday.

The attacks in Kramatorsk on Friday will add to a civilian death toll in Ukraine that has grown to more than 5,400 people since Russia invaded the country in February, according to the latest updates from the Office of U.N. High Commissioner for Human Rights. Since the war began, more than 7,400 civilians have been injured in Ukraine, including hundreds of children, according to the U.N.
