Thirty-six mercenaries have been killed, Hrytsak said.
As UNIAN reported, Hrytsak said earlier that the SBU had established the involvement of PMC Wagner in armed conflicts in Donbas and Syria.
"To date, we have identified 1,587 people who are members of PMC Wagner. The total number we see now is about 5,000 people. The geography of their deployment is Ukraine (occupied areas in Donbas; June 2014-August 2015) and Syria (the cities of Homs, Hama, Latakia, Damascus, and Palmyra on August 15, 2015), the SBU's chief said.
The Wagner's training base is located in Krasnodar Krai, Russia.
