Photos which helped to identify the exact location:
Tweeter user 5urpher has identified the same site on the video posted by the separatists July 17, 2015 and pinpointed it on the map later. The freeze-frame from this footage will be superimposed onto the map to compare locations further in the article.
"One can clearly see the windows of another building through the windows on one of the pictures, which have also helped us to identify the location," the article reads.
The similarity of the interior of the premises on the photo with the ones in the mentioned above footage is clear.
