Officials say 116 Ethiopian troops arrived Monday in Sudan, joining the more than 200 Ethiopian forces who have arrived since Saturday, according to a release from the U.N. Office for the Coordination of Humanitarian Affairs.

The deployment of Ethiopian troops is part of an effort to support peacekeeping and stability efforts in the volatile Darfur region.

The Ethiopian forces, who will operate in the West Darfur areas of Kulbus and Silea, are expected to provide engineering support for a "water installation and the erection of tents and electric power lines," the release said.
