The group suffered reverses in other parts of Libya during this period , including in Derna , Benghazi , and Sabratha . In June 2015 , clashes erupted in Derna between ISIL and the rival Shura Council of Mujahideen in Derna supported by the Libyan Air Force , which caused heavy casualties on both sides and led to ISIL forces being driven out of their strongholds in the city the following month . In November 2015 , a US air strike killed ISIL 's leader in Libya , Abu Nabil al Anbari . He was succeeded by Abdel Qader al-Najdi . In early 2016 , the Khalifa Haftar-led Libyan National Army , reportedly with the assistance of French Special Forces , captured parts of Benghazi that had been held by ISIL for months . In February 2016 , a U.S. air strike targeted an ISIL training camp near Sabratha , killing more than 40 people including the Tunisian ISIL member Noureddine Chouchane , linked to the 2015 Sousse attacks , as well as two Serbians who had been kidnapped by ISIL in 2015
