The Islamic State never has and never will target and kills unarmed civilians. When cases of killing civilians were proven in Islamic State courts, the accused, sometimes even their own fighters, were executed.
...Regarding the fleeing of refugees to mountains, (refer to point 1 regarding killing of civilians) the Islamic State would not fight or kill those unarmed civilians, and if they so wish, they can return. It is not the fault of the Islamic State when they have fled to the mountains with a false notion that the Islamic State kills civilians. In fact Yazidis live in peace in Mosul which is currently controlled by the Islamic State.
ISIS today took control of the largest Christian town Qaraqosh, between Mosul and Erbil (aka Arbil or Irbil), the capital of Kurdistan.
The onslaught saw the Sunni extremist Islamic State of Iraq and Greater Syria (ISIS) extend its writ over northern Iraq and move within striking distance of autonomous Kurdistan, in one of the most dramatic developments of the two month-old conflict.
ISIS militants moved into Qaraqosh and other towns overnight after the withdrawal of Kurdish peshmerga troops, who are stretched thin across several fronts, residents said.
...The ISIS advance means jihadists are now within striking distance, in some areas barely 20 kilometers, of the official border of the Kurdish region and 40 kilometers from Arbil.
McClatchy calls it Kurdistan's Last Stand. Exxon and another oil company have withdrawn their personnel from Arbil.
While the U.S. may provide military aid to the Yazedis on the mountain in Sinjar, it is not likely it will engage militarily in Arbil. The U.S. says (correctly in my view) there is no military solution to Iraq.
“There are no military solutions to the problems of Iraq,” he told reporters. He said the United States would move to protect American personnel but that American military action “would have to be closely tied to Iraqi political reforms.”
