Ukraine and Russia exchanged another group of ill and severely wounded servicemen on Thursday, officials from both countries said. All of the Ukrainian troops need treatment, Ukraine's President Volodymyr Zelenskiy said in a message on the Telegram messaging app that did not go into details on the numbers involved.

The prisoners of war (POWs) were released as part of a prisoner exchange with Russia agreed upon during recent peace talks in Istanbul, the Coordination Headquarters for the Treatment of the POWs said.

Ukraine and Russia carried out another exchange of prisoners of war as agreed in the 2 June Istanbul talks. Kyiv has not revealed how many Ukrainian defenders have been exchanged at each stage, saying only that the Thursday swap focused on severely wounded soldiers.
