Muslims have two main sects which are Sunnis and Shi'as (shiite). Both of them share the same principles but they have different veiws about the correct method to conduct them and different perspectives about the ways went around in certain incidents hundreds of years ago. We find accumulation of certain sect in one location but as for Iraq we find all these sects living there. Kurdishs are also living in Iraq. Most of them live in northen Iraq, part of Syria and part of Turkey. I think that they are not Arabs but mostly Muslims for sure. Turkman... do you mean Turkish???
