Russia and Ukraine agreed to a new prisoner exchange after their delegates met for a second round of renewed peace talks in Istanbul on Monday, but there was no sign the warring sides were any closer to reaching a ceasefire deal than they were when direct negotiations were restarted a month ago.

We assume that it will probably be 1,200 people on each side, and this will again be the largest exchange of prisoners of war,' says Vladimir Medinsky

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.
