The transfer of the prisoners was monitored by member of the Verkhovna Rada Committee on Human Rights Iryna Suslova and the OSCE Special Monitoring Mission (SMM) to Ukraine.
According to Kryklyvenko, over 500 appeals from prisoners' families requesting the transfer of their relatives to the government-controlled territory remain unaddressed. "It has not yet been possible to establish contacts with Luhansk [region whose part is also occupied by Russia]," he added.
As UNIAN reported earlier, Ukraine on December 27, 2017, extradited 233 individuals who were imprisoned on charges related to the Donbas war and were serving their sentences in Ukrainian prions, to Russian-backed militants in Donbas. In turn, 73 Ukrainians (32 prisoners of war and 41 civilians) were released by the other side.
