Syrian rebels and execution of civilians

"Mass executions of civilians and of fighters who were no longer participating in hostilities were reported in the northern cities of Aleppo, Idlib and Raqqa. They were carried out by armed opposition groups in Syria, in particular by the Islamic State of Iraq and Syria, Ms. Pillay said in a statement, citing what she described as reliable testimony by witnesses."  1) Notice that the dominant narrative of Western governments and media have followed the narrative of Syrian exile opposition whereby Nusrah Front has suddenly become a moderate force. Note that killing of civilians is now pinned exclusively on ISIS. 2) Yesterday, Nusrah Front took responsibility for a car bomb in Hirmil and I did not see a reference to that in Western media.  3) No matter who is up or down, Western media will strive to make the militia that receives Saudi cash as moderate and secular.
