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 AP
