BENGHAZI — At least nine fighters were killed in clashes on Friday between Daesh (the so-called IS) and another Islamist force in the eastern Libyan city of Derna, a source in one group said. Fighting had first erupted in Derna — a long-time gathering point for militants — on Tuesday after a leader in the Islamist umbrella group Majlis al-Shura was killed. At least 20 people were killed. New clashes broke out in one district on Friday and nine fighters were killed, the source said. No more details were immediately available. Daesh and other militant groups have thrived in Libya since two rival governments began fighting for control, leaving a security vacuum four years after Muammar Gaddafi's ouster. — Reuters
