Do these Iraqi Arabs look more Arabian or Mesopotamian?

There's a lot of varying looks there. I'd say the majority look Arab, not native pre-Arab. Some of those men are obviously foreginers, one in particular looks Yemeni to me. It's from ISIS so likely a lot of those men are foreign born mujahideen

I would say a mix of both with even some Iranid elements.
