A priest house and community hall for local Christians was constructed by the Supreme Committee of Christian Affairs by December 2012. The town had an estimated population of 11,498 in 2013. Most of the town's population of 16,000 people fled during the Islamic State of Iraq and the Levant (ISIL) offensive in August 2014, and under 500 men remained to defend Ain Sifni under the leadership of mayor Mamo al-Bagsri. Prior to the ISIL offensive, Ain Sifni was inhabited by 700 families, of which 80% were Yazidi, 10% were Christian, and 10% were Muslim. Humanitarian aid was delivered to Ain Sifni by the Assyrian Aid Society in November 2014.
