KYIV (Reuters) -Ukraine and Russia agreed at talks in Istanbul on Monday next week to give each other lists of people they want included in a planned prisoner of war swap, Ukrainian President Volodymyr Zelenskiy said. Zelenskiy told an online news briefing that negotiators for Russia and Ukraine agreed to exchange 1,000 prisoners each, with the possibility of swapping an additional 200 POWs. Zelenskiy also said Ukrainian negotiators gave their Russian counterparts a list of nearly 400 children it wanted Russia to return home to Ukraine, but that the Russian delegation agreed to work on returning only 10 of them.
