Ukrainian officials on Friday reported Russian strikes across the Donetsk, Luhansk and Kharkiv regions in eastern Ukraine, amid warnings of a major Russian offensive in the coming days.
The situation in the region was "getting more tense," Pavlo Kyrylenko, head of the Donetsk regional military administration, said in a statement on television. "The shelling, airstrikes have increased. Since yesterday in the north of the Donetsk region on the border with Kharkiv region, there have been attempts of breakthrough."
But the attacks were repelled, he added.
CNN was not immediately able to verify the battlefield situation in that region.
Oleh Syniehubov, the head of the Kharkiv region military administration, reported shelling of residential areas of Kharkiv. He said at least 34 people were injured, including three children, and seven people were killed, including a 7-month-old baby.
