The Ukrainian air force says Russia launched 479 drones at the country in the war’s biggest overnight drone bombardment

In addition to the 479 drones, 20 missiles of various types were fired at different parts of Ukraine from Sunday to Monday, according to the air force, which said the barrage targeted mainly central and western areas.

Russia and Ukraine exchanged prisoners of war under the age of 25 on Monday in emotional homecoming scenes, the first step in a series of planned prisoner swaps that could become the biggest of the war so far.
