The Kremlin says it's still in talks with Kyiv over the return of the bodies of Ukrainian soldiers.
In an update this morning it said some bodies are still waiting inside refrigerated trucks for a handover.
It added that there is "no understanding" of how many dead Russian soldiers will be handed over by Ukraine.
Yesterday, groups of wounded and seriously wounded Ukrainian and Russian soldiers under the age of 25 were exchanged. It was the first stage in a handover agreed at talks between Kyiv and Moscow in Istanbul last week.
