Khartoum - Four peacekeepers are missing in Sudan's troubled Darfur region after a flash flood hit while they escorted an aid mission, Unamid said on Monday.
"A Unamid rescue team from El Geneina, West Darfur, found two peacekeepers alive while a search is ongoing to locate the other four," an official of the African Union-United Nations Mission (Unamid) told AFP.
Unamid did not release the nationality of the troops involved.
The six were swept away "by a powerful current" while escorting the World Food Programme (WFP) to Misterei, about 50km southwest of El Geneina, the West Darfur state capital near Chad, the official said requesting anonymity.
"The incident occurred while the peacekeepers attempted to pull out their truck which was stuck in the mud of a river valley", the official added.
Floods across Sudan this month have killed about 50 people and affected more than 500 000, according to government figures.
