Russia and Ukraine exchanged hundreds more prisoners on Saturday as part of a major swap that amounted to a rare moment of cooperation in otherwise failed efforts to reach a ceasefire. The exchange came hours after Kyiv came under a large-scale Russian drone and missile attack that left at least 15 people injured.

Ukrainian President Volodymyr Zelensky and Russia’s defence ministry said each side brought home 307 more soldiers a day after each released a total of 390 combatants and civilians. “We expect more to come tomorrow,” Zelensky said on his official Telegram channel. Russia’s defense ministry also said it expected the exchange to be continued, though it did not give details.
