Libya has been riven by conflict between the rival parliaments since mid-2014. Tribal militias and jihadist groups have taken advantage of the power vacuum. Most notably, radical Islamist fighters seized Derna in 2014 and Sirte in 2015 in the name of the Islamic State of Iraq and the Levant. In early 2015, neighbouring Egypt launched airstrikes against ISIL in support of the Tobruk government.
