AP PHOTOS: Russia and Ukraine swap hundreds more prisoners hours after a massive attack on Kyiv

CHERNYHIV REGION, Ukraine (AP) — Russia and Ukraine exchanged hundreds more prisoners 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 happened hours after Kyiv came under a large-scale Russian drone and missile attack that injured at least 15 people. Authorities in Ukraine said the capital again came under a combined drone and missile attack that started Saturday night and stretched into Sunday morning.
