Yes. It's part of an overall pattern of distinguishing between services and security and providing humanitarian assistance along ethnic lines. The best single example of that is the situation I briefly mentioned a moment ago, in which a Dinka population is moved into an area that is then provided with humanitarian assistance, while the non-Dinka population that is moved out is left without assistance.
I'm not saying it's a uniform situation, but there are certainly many instances of this around the country.
