CAIRO—Two days of tribal fighting in Sudan’s south killed at least 220 people, a senior health official said Sunday, marking one the deadliest bouts of tribal violence in recent years. The unrest added to the woes of an African nation mired in civil conflict and political chaos.
Fighting in Blue Nile province, which borders Ethiopia and South Sudan, reignited earlier this month over a land dispute. It pits the Hausa tribe, with origins across West Africa, against the Berta people.
