United Nations officials say four peacekeepers are missing in Sudan's Darfur region after being swept away by recent floods.
The peacekeepers were escorting an aid convoy when a "powerful current" swept them away, said Rania Abdulrahman, a spokeswoman for the United Nations Mission in Darfur.
Another two peacekeepers were found alive by a rescue team, she said.
The joint United Nations-African Union peacekeeping mission in Darfur, Unamid, is one of the largest in the world, with approximately 20,000 soldiers and police.
The peacekeepers were traveling with a World Food Programme (WFP) convoy when a flash flood hit,
Abdulrahman told the BBC.
The incident occurred as the peacekeepers “attempted to pull out their truck, which was stuck in the mud of a river valley," she said.
All seven WFP staff members who were in the convoy — five Sudanese and two foreigners — are safe, according to WFP spokeswoman Amor Almagro.
The United Nations. has not released the nationalities of the missing peacekeepers.
Almost 50 people have died this month as a result of large-scale flooding that has engulfed Sudan.
