Ukraine's security service, the SBU, is going to interview the released hostages, previously held in captivity by Russian militants in Donbas. According to the service's head Vasyl Hrytsak, the task is to get the utmost information regarding those who still remain captive in the occupied territories.
Answering the question about the terms of the next stage of the exchange, Hrytsak said he hoped it could take place 'in the near future.'
'We will work with the guys who returned home; we'll ask them if they had any contacts with those currently credited as missing or captured - by our estimates, that's 402 people. Perhaps, we'll be able to find out their whereabouts,' Hrytsak said.
'We will, of course, interview them. ask them about the circumstances and conditions of their captivity. There's such thing as counter-intelligence interrogations, and we'll conduct them. We resort to such actions when something about a person's captivity still remains unclear,' the official added.
