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.
