SBU starts locating militants' concentration camps and mass graves in Donetsk and Luhansk regions - Lubkivsky

Ukraine's Security Service (SBU) has started the process of locating concentration camps set up by illegal armed groups and mass graves dug by them in the east of the country, an advisor to the SBU chief, Markiyan Lubkivsky, has said.

"We have started a very long and complicated process of identifying the placements of concentration camps and mass graves in Donetsk and Luhansk regions," he said at a briefing on Friday, adding that the issue concerns Ukrainian military and civilian graves.

He said that special services had actually started to make a "death map," which depicts crimes against humanity committed by the militants. He said that this was only the beginning and that the map was still incomplete.

To this end, SBU uses data from other agencies, information from different sources, including from local residents in the eastern parts of the country, as well as satellite images, Lubkivsky said.
