Clashes renewed Saturday between the Libyan Army and Fajr Libya (Libya Dawn) militia alliance, which controls most of the capital, as well as a part of the city of Misrata.
Loud explosions are heard in a number of areas, local sources said on Saturday.
Libya was plunged into civil war since the ouster of Muammar Gaddafi in 2011. Two rival governments each backed by armed militias have been battling for control of key cities and the nation’s oil wealth.
Fajr Libya launched a bloody offensive in December to seize control of key oil terminals but was repelled by the army.
Violence has left hundreds of Libyans killed, thousands wounded, and has displaced hundreds of thousands of civilians. Most foreign diplomats have fled the country after their embassies shut down last year.
