Fighters loyal to the Libyan internationally-recognised Government of National Accord (GNA) fire a heavy machine gun during clashes against forces loyal to strongman Khalifa Haftar, on May 21, 2019 in the Salah al-Din area south of the Libyan capital Tripoli. - Despite a UN embargo, weapons are still flowing into Libya where an assault on the capital by Haftar threatens to escalate into a proxy war between regional powers. Haftar, whose self-styled Libyan National Army (LNA) is allied with an administration in eastern Libya, is supported especially by Egypt and the United Arab Emirates (UAE).
