On 11 March, ISIL threatened on loudspeakers to behead any civilian who tries to leave Mosul. The announcement came one day after US planes dropped paper pamphlets into the city, warning of an imminent military confrontation, and advising all civilians to evacuate the city.[35] Also, on the same day, the US-led Coalition carried out five airstrikes in and around Mosul, which struck an ISIL tactical unit, an ISIL outpost, and destroyed an ISIL armored vehicle.[2]
