“We are waiting for the Minsk meeting. After the meeting, everything will be clear. We want to exchange captives ‘all for all’,” Vasily Vovk told a briefing.
The security service is ready to release all members of self-defense forces, but not those with “blood on their hands", he said, adding: “There are about ten such people, no more.”
The eastern region's militia hold 684 people captive, he said.
Kiev authorities earlier stated they were ready for the “all for all” exchange, but after the meeting in Minsk.
The head of the committee of the self-proclaimed Donetsk People’s Republic for refugees and captives, Daria Morozova, said on Thursday Kiev for three weeks could not explain why the exchange was postponed. She linked it with organizational chaos among Ukrainian security authorities.
