Sudan: About 34,000 people flee South Sudan clashes

About 34,000 southern Sudanese have fled their homes after tribal clashes over land, water and cattle in recent weeks, a humanitarian official said, adding to southern troubles before independence in July. The oil-rich south voted overwhelmingly to separate from the north in a January referendum, promised as part of a 2005 peace deal that ended decades of civil war in Sudan. At least two million died in the war, which destabilised much of the region.
