Amid ongoing conflict, Russia and Ukraine exchanged drone attacks on each other's capitals, resulting in injuries and airport restrictions. Simultaneously, a significant prisoner swap occurred, with hundreds of soldiers released on each side.

Russia and Ukraine began a major prisoner exchange Friday, swapping hundreds of soldiers and civilians in the first phase of an exchange that was a moment of cooperation in otherwise failed efforts to reach a ceasefire in the 3-year-old war.

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