In a region with a history of genocide, weeks of intense fighting between rival military factions in South Darfur have left hundreds dead and sent thousands fleeing.
Hundreds of thousands fled a grisly civil conflict years ago to settle in Sudan, to the north. With war now raging there, they are streaming home to a country ill-prepared to take them back.
Hundreds have been killed in the western Darfur region since the nationwide conflict in Sudan began, raising fears of protracted warfare in an area already torn by decades of genocidal violence.
The United Nations predicted that the figure would rise to more than 800,000 by year end, in addition to more than 300,000 people internally displaced already.
The clashes have killed more than 400 people and injured thousands more. Those displaced are streaming into nations such as Chad, Egypt and South Sudan, adding to a refugee crisis in the region.
