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.

A planned exchange of Russian and Ukrainian prisoners of war failed to take place on Saturday, with Moscow accusing Kyiv of postponing the swap at the last minute, something Ukrainian officials dismissed as “dirty games” from the Kremlin.

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