Ukraine denies postponing prisoner swaps as Russian strike on Kharkiv kills four

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. Later on Saturday, Russian aircraft carried out another bombing raid on Kharkiv, killing one civilian and injuring more than 40, which Ukrainian President Volodymyr Zelenskyy called "another brutal murder". Separately, Russian officials said a Ukrainian drone attack in the Moscow region wounded two people.
