The crisis in Sudan's western Darfur region is often portrayed as a simple conflict between Arabs and Africans, but the World Food Programme's Greg Barrow says the reality on the ground is much more complex:
There are few sadder sights to behold in South Darfur state than the 5,000 members of the Dinka community living in a camp on the edge of the village of Muhajaria.

They are among the tens of thousands of Dinka who fled to the region in the late 1980s to escape attacks from Arab horsemen, or Muraheleen, who were rampaging across the Dinka homeland in the remote and barren south Sudanese province of Bhar Al Ghazal.

Today, they are cursed with the dreadful irony of having fled one conflict zone only to find themselves stranded in another.

For more than 15 years, they have been adrift and bereft, carving out a pittance of an income by working as sharecroppers, cleaners and builders.

They are far from their homes, and have lost the wealth that they once preserved in the shape of their majestic cattle herds.
