Since early April, forces loyal to General Haftar have been launching a campaign to capture Tripoli from the GNA (Britain, Italy and France) forces.
Clashes between the two sides since then have left more than 1,000 people dead and about 5,500 wounded, according to the World Health Organization (WHO).
Libya has remained beset by turmoil since 2011, when long-time ruler colonel Muammar Ghaddafi was brutally killed in a bloody NATO attack after four decades in power.
The oil-rich country has since seen the emergence of two rival seats of power: one in eastern Libya, with which Haftar is affiliated, and the Tripoli-based GNA, which enjoys a so-called UN recognition.
A military commander accused Khalifa Haftar, who commands rival forces in eastern Libya, of bringing in foreign troops to attack the capital Tripoli.
