in April 2019, Libyan National Army (LNA) forces launched an offensive to seize the capital, Tripoli, from the UN-recognized GNU (aka Government of National Accord or GNA); the GNU and its local supporting militia forces forced the LNA to withdraw by June 2020; at the signing of a UN-sponsored ceasefire in October 2020, GNU and LNA forces were separated by a line of control running roughly from the coastal city of Sirte south to the vicinity of Al Jufra and Brak; as of late 2021, this line had grown increasingly fortified; in April 2021, the UN Security Council endorsed plans to deploy civilian ceasefire monitoring personnel at the request of the Libyans
outside actors have played a large role in the fighting in Libya on both sides:
as of 2021, GNU forces were backed militarily by Qatar and Turkey; Turkey has been the chief supporter; it signed a security agreement with the GNU in 2019, and Turkey’s aid was assessed as vital in turning back the LNA offensive in 2019-2020; Turkey’s support has included air defense, unmanned aerial vehicles (aka drones), equipment, weapons, training, and military personnel, including advisors, technicians, and equipment operators; in addition, Turkey has provided as many as 5,000 mercenary fighters from Syria
as of 2021, LNA forces (aka Libyan Arab Armed Forces, LAAF) have received varying amounts of military support from Chad, Egypt, France, Jordan, Russia, Sudan, and the United Arab Emirates (UAE); Russia, Sudan, and the UAE have been the most active; Russia has provided equipment, weapons, aircraft, and air defense support, as well as an estimated 5,000 Russian mercenaries/private military contractors and Russian-sponsored Syrian mercenary fighters; Sudan reportedly provided at least 1,000 troops from its Rapid Support Forces in 2019-2020 and more than 1,000 Sudanese mercenaries were present in Libya as of late 2021; the UAE provided equipment, supplies, weapons, and air support, including air strikes from manned and unmanned aircraft; meanwhile, Egypt has provided arms, supplies, and training, as well as facilitated both Emirati and Russian operations in Libya by allowing them to use the country’s western bases and to transport arms over the border
as of late 2021, it was estimated that as many as 20,000 third-country nationals were involved in military operations in Libya, despite the confidence building measure of the October 2020 ceasefire that called for all foreign forces to leave the country by early 2021; in addition to the military and proxy forces provided by Russia, Sudan, and Turkey, foreign fighters from Libya’s neighbors (Algeria, Chad, Egypt, Mali, Niger, and Tunisia, as well as Sudan) have travelled to Libya since the civil war began in 2011 to support various armed groups, including those aligned with the GNU and the LNA, as well as the Islamic State of Iraq and ash-Sham and Al Qa’ida terrorist group affiliates operating in Libya; most of these fighters arrived as individuals, but rebel groups from Chad and Sudan were also reportedly involved in the fighting
