I refuse to believe ISIS is behind this and refuse to believe K.S.A is stupid enough to attack Iran directly. These attacks are too sophisticated and well organised. ISIS would just blow them selves up in a crowded area, and there are many in Tehran. And since when did ISIS use woman terrorists and cyanide pills? This reeks of CIA/Mossad taking advantage of the Qatar situation trying to push S.A and Iran into a huge war. Dragging all muslim countries
