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. The past year, ISIL _ has taken over swaths of territory in Syria, particularly in the east. It has increasingly clashed with other factions, particularly an umbrella group called the Islamic Front and with Jabhat al-Nusra, or the Nusra Front, the group that Ayman al-Zawahri declared last year to be al-Qaida’s true representative in Syria. That fighting has accelerated the past month. (AP Photo/militant website, File)
