"Further 307 Russian soldiers have been released", it says according to Russia, with the addition that the country in exchange has freed 307 prisoners of war who are sent home to Ukraine. Zelensky confirms the figure.
"We expect more tomorrow", the president announces.
The agreement that each side will release around 1,000 prisoners of war is one of the few concrete results of the recent peace talks in Istanbul.
The exchange began on Friday, and the hope is that it will be completed on Sunday.
