FILE - This undated file image posted on a militant website on Tuesday, Jan. 14, 2014 shows fighters from the al-Qaida linked Islamic State of Iraq and the Levant (ISIL) marching in Raqqa, Syria. Once a vibrant, mixed city considered a bastion of support for President Bashar Assad, the eastern city of Raqqa is now a shell of its former life, transformed by al-Qaida militants into the nucleus of the terror group's version of an Islamic caliphate they hope one day to establish in Syria and Iraq. In rare interviews with The Associated Press, residents and activists in Raqqa describe a city where fear prevails, music has been banned, Christians have to pay religious tax in return for protection and face-veiled women and pistol-wielding men in jihadi uniforms patrol the streets.
