Attack occurs hours after Russia and Ukraine begin prisoner exchange in deal seen as first step towards ceasefire

Russia has launched a large-scale drone and missile attack at Kyiv, injuring 15 people in one of the biggest assaults on the Ukrainian capital since the beginning of the war three years ago.

The attack came in waves, with Russia launching 14 ballistic missiles and 250 drones in the early hours of Saturday morning, although Ukrainian forces shot down six missiles and stopped most of the drones before they reached Kyiv.
