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.

Russia has targeted Ukraine for a second consecutive night with drones and missiles, killing at least 12 people as the two countries pursue a major prisoner swap. Ukraine's air force said on Sunday that Russian forces attacked Ukrainian regions with 298 drones and 69 missiles overnight, one of the largest aerial attacks of the war. "Most regions of Ukraine were affected by the hostile attack. Enemy air strikes were recorded in 22 areas, and downed cruise missiles and attack UAVs (drones) fell in 15 locations," the air force said on Telegram. Ukraine's security service reported that at least four people were killed and 16 were injured in the capital, Kyiv.
