U.N. peacekeepers patrol in Abyei, Southern Sudan, on Friday, March 11, 2011. Scores of villagers have died in recent fighting in Southern Sudan despite the presence of 10,000 U.N. troops mandated with protecting civilians. Now, internal documents say U.N. officials have ordered the peacekeepers not to operate in an area where civilians are at risk in upcoming battles, after being asked to avoid the region by the south's military.
