Sudan has a conflict in the Darfur area of western Sudan. The Khartoum government had, in the past, given sanctuary to trans-national Islamic terrorists, but, according to the 9/11 Commission Report, ousted al-Qaeda and cooperated with the US against such groups while simultaneously involving itself in human rights abuses in Darfur. There are also transborder issues between Chad and Darfur, and, to a lesser extent, with the Central African Republic.
