A delegation from the Toubou tribe, one of several semi-nomadic African tribes in southern Libya, traveled to Tripoli on Nov. 27 for talks to help resolve tensions after a Zuwaya tribesman allegedly killed a Toubou tribesman, Libyan media reported. Violence between the Toubou and Zuwaya tribes around the southeastern town of Kufra has existed since the Gadhafi era, but like southern Libya's other tribal conflicts, it was repressed by the Gadhafi regime. Since Gadhafi was removed from power in October 2011, tribal violence in southern Libya has intensified. In the absence of a strong central government in Tripoli, the southern tribal conflicts threaten critical energy installations and key infrastructure. Tribal disputes are just one of many challenges the Libyan provisional government will face in the future . But of these tribal disputes, the Toubou-Zuwaya conflict is particularly important because of the threat it poses to oil and water resources.
