The hourslong raids, involving hundreds of drones, were a reminder that any diplomatic resolution to the conflict remains far off.

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.
