Russian military officers are often involved in tortures of Ukrainian prisoners in Donbas conflict area. The head of Ukrainian Security Service Vasyl Hrytsak reported this on air of 112 Ukraine TV channel.

“They either directly tortured Ukrainians or organized such things with the help of those who fought on the side of terrorists," he said.

Hrytsak reported on documented cases of torture on the territory of Russian Federation.

"Our captured soldiers were transported to Russia, where, under the command of the security services, as a rule, it was FSB, they interrogated, tortured them brutally, and then returned back to Donbas," the SBU head said.

Several offenders were identified.

"We identified many of those who tortured our fighters, and I am convinced that the time will come when we will be able to bring them to justice. We also know the code names of some of these people," he said.

As it was reported earlier by Vasyl Hrytsak, 3,224 prisoners were released from the occupied territories of Donbas by the Ukrainian special services since the beginning of the Donbas conflict. The law enforcers were shocked by the state of the prisoners, he said.

Also, Ukrainian citizens released from the captivity of the pro-Russian militants of Donbas started to receive the compensations.
