That's a very good question. I have to say I can't give a precise answer. What I know is that the Yazidis in southeast Turkey are hosted in municipal camps and have not been registering with the provincial authorities. Now, is this a matter of their not knowing they have to do it, and in that sense this would apply to all the refugees, or is this something that the Yazidis themselves don't want to do? This I have to find out.
