This weekend, Libya opened peace talks aimed at ending conflict in Sudan's Darfur region. The Sudanese government announced an immediate cease-fire Saturday, but prospects for a settlement are clouded.
Hundreds of thousands of Sudanese civilians have been killed in the fighting in Darfur, with millions more displaced. The fighting is largely split along ethnic lines. It involves the Sudanese army, its Arab militia allies and various black African groups.
The Sudanese government quickly proclaimed the unilateral cease-fire at Saturday's talks — something it has done before. But two of Darfur's main rebel groups are boycotting the conference, and that casts doubt on prospects for success.
