Hundreds of people have been killed since last week in clashes between rival tribes over control of territory in Libya. Libya's ruling National Transitional Council has not been able to pull the country together since a U.S. military and NATO led operation help to topple the dictator Muammar Gaddafi last October. Violence broke out late last week in the remote city of Al Kufra and has continued since. The challenge --policing the country's thinly populated desert.
