Fresh fighting has erupted between rival Libyan militias on the outskirts of the Libyan capital, following deadly clashes on November 15.
The violence in Tripoli's eastern suburb of Tajoura on November 16 pitted militiamen against fighters from the city of Misurata.
Prime Minister Ali Zeidan urged rival militias to stay out of Tripoli, adding, "It would have negative and catastrophic consequences."
Officials say 42 people died and 400 others were wounded in clashes o November 15.
The bloodshed began when protesters marched on the headquarters of the Misurata militia to demand that it leave Tripoli, and were fired upon.
Demonstrators fled but then returned, heavily armed, to attack the compound.
Two years after the fall of Muammar Qaddafi's regime, the government is struggling to contain militias who control parts of Libya.
