The ISIL insurgency in Iraq is an ongoing low-intensity insurgency that began in late 2017 after the Islamic State of Iraq and the Levant (ISIL) lost territorial control in the War in Iraq of 2013 to 2017. ISIL and allied White Flags fought the Iraqi military (largely backed by the United States and other countries conducting airstrikes against ISIL) and allied paramilitary forces (largely backed by Iran).
