Sudan: Tribal rivalries threaten all-out war

Cattle-rustling raids and revenge attacks in southern Sudan killed at least 30 people, according to reports last week. Tribal rivalries in Lakes State erupted into "open war" last weekend, according top deputy-state governor, David Noc Marial. Traditional conflicts, often waged over cattle, have been exacerbated by the availability of weapons left behind after the north-south civil war which ended in 2005. Aid groups suggest 2,500 people have been killed in ethnic violence in southern Sudan since the start of 2009, prompting fears for the April elections, promised in the 2005 peace deal.
