Russia and Ukraine exchanged hundreds more prisoners on Saturday as part of a major swap that amounted to a rare moment of cooperation in otherwise failed efforts to reach a ceasefire. The exchange came hours after Kyiv came under a large-scale Russian drone and missile attack that left at least 15 people injured.

Officials said Russia attacked Ukraine with 14 ballistic missiles and 250 Shahed drones overnight while Ukrainian forces shot down six missiles and neutralized 245 drones — 128 drones were shot down and 117 were thwarted using electronic warfare.

The Kyiv City Military Administration said it was one of the biggest combined missile and drone attacks on the capital.
