African Union (AU) and United States mediators are trying to reconcile the divided leadership of the largest rebel group in Darfur ahead of the resumption of the peace talks later this week, an AU official said. The leaders of the Sudan Liberation Movement/Army (SLM/A) are under pressure to resolve their internal differences and present a united front at the next session of the delayed peace negotiations in the Nigerian capital, Abuja, which had been scheduled to start on 21 November.
