An ISIS suicide squad on Sept. 18 penetrated an air base on the outskirts of Tripoli that serves as the Libyan capital's only working airport in an attack on the Islamist militia that was defending the facility. The four ISIS attackers were killed in the clash, and at least three members of the Special Deterrence Force, which is loyal to the Islamist-led Tripoli-based government. The attack comes as the UN special envoy to Libya, the Spanish diplomat Bernardino Leon, is seeking to broker out a power-sharing deal between the Tripoli government and Libya's recognized government, now exiled in Tobruk. Despite the talks, fighting continues between the rival governments, especially in the contested city of Benghazi. The UN Support Mission in Libya (UNSMIL) on Sept. 20 strongly condemned new air-strikes by Tobruk-loyal forces in Benghazi, and called for an immediate ceasefire. "The timing of airstrikes clearly aims at undermining the ongoing efforts to end the conflict," the Mission said of the pervious day's escalation. The statement noted that more than 100,000 have been displaced by the conflict that has raged in the city for over a year now, with residential neighborhoods reduced to rubble.
