Because of the resurgence of violence, the United Nations Refugee Agency has hurriedly built this camp for the Darfuris, and it is saving lives. But, while the world is willing to spend more than $1 billion annually assisting survivors of attacks in Darfur, it seems unwilling to stand up to President Omar Hassan al-Bashir of Sudan or even speak out very forcefully.

The world has moved on, but the killing continues.

This is the last stop on my annual win-a-trip journey, in which I take a student on a reporting trip to the developing world. The winner, Erin Luhmann of the University of Wisconsin, and I hope to shine a bit more light on the continuing slaughter in Darfur — and on the courage and resilience of the survivors.

Sheltering under one tree here in the Abgadam camp were three small children, all orphans from bloodletting in Darfur. The oldest is a 9-year-old girl named Asiya who is now effectively mother to her brothers, Muhammad, 7, and Yasin, 2. The mother and father were shot dead in their home by a Sudanese government-backed militia, villagers say.

The victims in this year’s wave of attacks are members of two Arab ethnic groups that have not previously been singled out in Darfur, the Salamat (including the three orphans) and the Beni Hussein.

Sudan apparently drove out the Beni Hussein because government officials covet gold that has been discovered on their land. It seems to be expelling the Salamat because it distrusts them and prefers to give their land as a reward to a more loyal Arab group, the Miseriya.
