Two successive nighttime Russian attacks on the Ukrainian capital of Kyiv came amid a major prisoner exchange between the two countries.

Russia launched a major attack on the Ukrainian capital Kyiv and killed at least 13 people in strikes across the country as the two sides released hundreds more prisoners on the second day of a major prisoner exchange.

Russia and Ukraine swapped hundreds more prisoners on Sunday, the third and last part of a major exchange that reflected a rare moment of cooperation in otherwise failed efforts to reach a ceasefire in the more than three years of war.
