FILE – In this undated file photo released by a militant website, which has been verified and is consistent with other AP reporting, militants of the Islamic State group hold up their weapons and wave its flags on their vehicles in a convoy to Iraq, in Raqqa, Syria. IS, the ultra-extremist group responsible for some of the worst atrocities perpetrated against civilians in recent history, is on the verge of collapse. The group that brutalized residents living under its command for more than three years is fighting to hang on to remaining pockets of territory in Iraq and Syria, besieged by local forces from all sides.
