Ukraine and Russia traded almost 200 prisoners of war prisoners of war in a swap announced separately by both sides on Saturday, with the bodies of two British volunteers sent back to Ukraine.
Russian news agencies cited Moscow's defence ministry saying 63 Russian POWs had been freed, while Ukrainian president Andriy Yermak said 116 Ukrainians had been returned.
On Telegram, Yermak wrote that we returned 116 of our people, defenders of Mariupol, partisans from Kherson, snipers from the Bakhmut front and other heroes of ours.
Yermak said the bodies of British volunteer workers Andrew Bagshaw and Chris Parry had been sent back to Ukraine.
The couple were killed in eastern Ukraine last month during an attempted humanitarian evacuation, according to Parry's family.
Russia's Defence Ministry said the Russian servicemen included sensitive category persons whose exchange was made possible through the mediation of the United Arab Emirates UAE.
