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.

Russia claims Ukraine indefinitely postponed the release while Kyiv maintains it has been delayed until next week.

Seventeen people were wounded in a Russian drone strike on the eastern Ukrainian city of Kharkiv early Thursday, including children, a pregnant woman, and a 93-year-old woman, regional head Oleh Syniehubov wrote on Telegram.
