Footage released by the Libyan National Army (LNA) on Wednesday allegedly shows LNA forces after reportedly taking control over the Brigade N*42 base in Ain Zara, southern Tripoli.
Fighters from the LNA, led by Field Marshall Khalifa Haftar, can be seen celebrating and pulling victory signs while surveying the base.
Since erupting over a week ago, fighting over the Libyan capital between Misrata forces and the LNA has left at least 47 dead, including 9 civilians.
The LNA, which controls eastern Libya, is aiming to take over territory from the internationally recognised Government of National Accord (GNA) including Tripoli, as the country has been split between the two rival governments since 2014.
Approximately 4,500 Tripoli residents have so far been displaced due to the ongoing clashes, according to the UN Office for the Coordination of Humanitarian Affairs (UNOCHA).
