The African Union says it is temporarily suspending the deployment of troops to Sudan's troubled Darfur region because of a fuel shortage.
AU officials say the suspension will last several weeks.
The Associated Press reports the fuel shortage was caused by the closure of a refinery in Sudan's capital, Khartoum, for repairs. AU officials say heavy rains in Darfur are also hindering the deployment of troops as some roads have become impassable.
Several thousand AU troops and police officers are already in Darfur. The force is expected to number more than 7,000 when the deployment is completed.
The force is monitoring a cease-fire between Darfur rebels and pro-government Arab militia. The conflict has left 180,000 people dead and two million others displaced.
