Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Ukraine says that a large Russian drone-and-missile attack has targeted the eastern city of Kharkiv, killing at least three people and injuring 21

Ukraine denied Russian allegations on Saturday that it had indefinitely postponed prisoner swaps, accusing Moscow of "playing dirty games" after overnight Russian missile and bomb strikes on Kharkiv left three people dead and 22 injured.
