Here are more details of the prisoner release in Donetsk, from RFE/RL's news desk:
Pro-Russian separatists in Ukraine's eastern region of Donetsk have freed 16 Ukrainian prisoners of war.
The release happened on April 6 and the separatists said that it was a unilateral gesture.
Darya Morozova, the so-called ombudsman of the self-proclaimed Donetsk People's Republic (DNR), said the 16 were the last Ukrainian soldiers held as prisoners by the DNR.
The Ukrainian news website UNIAN posted a photograph of the soldiers boarding a bus.
Ukrainian President Petro Poroshenko confirmed on his Twitter account the release of "16 of our heroes" and said they were already on route to the town of Kramatorsk.
