this is one sided view, it is not telling the other side of the facts. Nuba mountain is part of what going to be north sudan and nubian they are every where in sudan with full privillage to their sudanese citizenship. What is happening now is being violated by the SPLM members who are not accepting the result of the governer election which has been approved by many international organizations. What the government try to do is to maintain rule of law, it is not ethinics cleaning which was is the label described by  only some Amercan institution to the situation in Darfur . My advice make your efforts to work towards peace and not try to divide people.
