Russia and Ukraine exchanged prisoners-of-war (POWs) on Saturday, the Russian defence ministry said, and Russia handed over the bodies of 1,200 dead Ukrainian soldiers to Kyiv.

The exchanges are part of agreements reached by the warring sides during talks in Istanbul earlier this month. Ukraine earlier on Saturday confirmed it had received the bodies of its soldiers killed in action.

However, Russian state media reported, citing sources, that Moscow had not received any of its war dead back from Kyiv, echoing a statement Russia made on Friday, when it said it had returned the bodies of 1,200 slain Ukrainian soldiers and received none of its own.

The Russian defence ministry did not say how many POWs were involved in the swap with Ukraine on Saturday, but it posted video showing its soldiers holding Russian flags and cheering before boarding a bus.

The Russian soldiers are in Belarus, where they are receiving medical treatment before transfer back to Russia, the defence ministry said.
