ISIL took complete control of Raqqa by 13 January 2014. ISIL proceeded to execute Alawites and suspected supporters of Bashar al-Assad in the city and destroyed the city's Shia mosques and Christian churches such as the Armenian Catholic Church of the Martyrs, which was then converted into an ISIL police headquarters and an Islamic centre, tasked to recruit new fighters. The Christian population of Raqqa, which had been estimated to be as much as 10% of the total population before the civil war began, largely fled the city.
