"Amnesty International also recorded at least three recent incidents when the separatist fighters applied extrajudicial executions to at least eight pro-Kyiv soldiers," he said at a press-conference.
Yankov noted that in general they know about four incidents with Ukrainian soldiers' executions.
These facts are confirmed by the eyewitnesses, medical records, evidences from the social networks and the media.
Most of the executions and tortures take place in unofficial locations of detention.
10 such places were found at the occupied territories of the Donetsk and Luhansk regions.
