Washington - U.S. military advisors are operating inside the city of Raqqa, Daesh's (ISIS) last major bastion in Syria, a U.S. official said Wednesday. The troops, many of them special operations forces, are working in an "advise, assist and accompany" role to support local fighters from the Syrian Democratic Forces as they battle Daesh, said Colonel Ryan Dillon, a military spokesman. The troops are not in a direct combat role but are calling in air strikes and are working closer to the fight than did U.S. forces supporting the Iraqi military in Mosul. "They are much more exposed to enemy contact than those in Iraq," Dillon said. He said the numbers of U.S. forces in Raqqa were "not hundreds." The operation to capture Raqa began in November and on June 6 the SDF entered the city. With help from the U.S.-led coalition, the SDF this month breeched an ancient wall by Raqa's Old City, where diehard militants are making a last stand. Dillon said the coalition had seen Daesh increasingly using commercial drones that have been rigged with explosives. The extremists employed a similar tactic in Mosul. "Over the course over the last week or two, it has increased as we've continued to push in closer inside of Raqqa city center," he said. The U.S. military is secretive about exactly how big its footprint is in Syria, but has previously said about 500 special operations fighters are there to train and assist the SDF, an Arab-Kurdish alliance. Additionally, Marines are operating an artillery battery to help in the Raqqa offensive.
