Russian officials say that Moscow is still awaiting confirmation from Kyiv on a planned exchange of 6,000 bodies of soldiers killed in action.

Russia's claims that Ukraine is delaying exchange of soldiers' bodies are untrue, Ukrainian officials said on Saturday, urging Moscow to stop "playing dirty games" and return to constructive work. Kremlin aide Vladimir Medinsky said on Saturday that Ukraine had unexpectedly postponed exchanging prisoners of war and accepting the bodies of killed soldiers for an indefinite period.

"In strict accordance with the Istanbul agreements, on June 6, Russia began a humanitarian operation to hand over to Ukraine more than 6,000 bodies of killed Ukrainian servicemen, as well as to exchange wounded and seriously ill prisoners of war and prisoners of war under the age of 25," Medinsky said on Telegram.
