In October 2014, the self-declared Islamic State of Iraq and the Levant (ISIL) took control of numerous government buildings, security vehicles and local landmarks in the Eastern Libyan coastal city of Derna. Although some media outlets reported the control as being absolute, rival groups like the al-Qaeda-affiliated Abu Salim Martyrs Brigade continued to control parts of the city. Clashes erupted between ISIL and an alliance of Islamist groups in June 2015, with ISIL retreating from Derna to outlying suburbs the following month. However, clashes continued between the Islamist alliance and the Tobruk-based government forces.
