Local council urges brigades of revolutionary fighters from outside Tripoli to leave the capital by December 20.
One person has died in fighting near the international airport in the Libyan capital, Tripoli, between a brigade calling itself “Libya’s National Army” and former rebels who control the facility.
The clashes came the same day the country’s governing National Transitional Council (NTC) held its first conference on national reconciliation.
The NTC has given armed groups in Tripoli until December 31 to disarm and leave the city.
The violence underscores the challenges the new leaders face as they attempt to govern the various armed groups that helped topple Muammar Gaddafi.
