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.

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

As Kyiv completed its largest prisoner exchange of the war on May 25, exchanging 1,000 Ukrainian POWs for 1,000 Russians, some spoke out on social media to criticize authorities for failing to return certain captives.
