...The fact that the so-called "Islamic State" Terrorists' deadly Attaks Target mainly Christian Towns and Kurds at Iraq etc., clearly shows that they are serving the interests of Turkey, (from whose Borders they have emerged from the start).
Indeed, among many other facts, it's also strange why that "Islamic State" Deadly Terrorists seem to have singled out the only notable Iraqi Town inhabited mainly by "Turcomans" and left it completely untouched, while, on the contrary, almost all other towns near and even around it have either been already invaded and occupied by ISIL or at least hardly hit and violently contested by its brutal pseudo-"Djihadists"...
