More intra-tribal fighting in Sudan, in the city of Khartoum no less. The Sudan government reports two groups belonging to the same south Sudan tribe, the Nuer (both groups living in Khartoum), have engaged in a series of deadly fights. The first occurred July 7, in a Khartoum market. Three died in that incident. Six more people were killed in fighting July 10-11. Sudan reported that Khartoum police have now arrested hundreds of Nuer. AFP said the fights began with a fistfight between two Nuer tribesmen in a refugee camp outside Khartoum. A fine on the defendant levied by a tribal court didn't satisfy the plaintiff. Out came guns, knives, canes, and spears, and the violence escalated.
