title: Ninety percent of Raqqa retaken from Islamic State - U.S. military
text: WASHINGTON (Reuters) - The U.S. military said on Tuesday that it could only confirm that about 90 percent of the Syrian city of Raqqa had been retaken from Islamic State militants, even as U.S.-backed forces declared victory there. The Syrian Democratic Forces (SDF), an alliance of Kurdish and Arab militias, said the fighting was over and it was clearing Raqqa s stadium of mines and any remaining militants. A formal declaration of victory in Raqqa, Islamic State s de facto capital in Syria, will soon be made once the city has been cleared of mines and any possible Islamic State sleeper cells, said SDF spokesman Talal Selo. The fall of Raqqa, where Islamic State staged euphoric parades after its string of lightning victories in 2014, is a potent symbol of the jihadist movement s collapsing fortunes.  Colonel Ryan Dillon, a spokesman for the U.S.-led coalition fighting Islamic State, said that about 100 fighters still remained in Raqqa and he expected the SDF to face resistance from remnants of militant group.  We are aware of the reports that ISIS has been defeated in Raqqa,  Dillon said, using an acronym for Islamic State.   However, clearance operations continue and we expect our Syrian Democratic Force partners to hit pockets of resistance as the final parts of the city is cleared,  Dillon said. He said that in the past few days, about 1,300 civilians had been  assisted to safety  by the SDF and about 350 Islamic State fighters had surrendered in Raqqa. Even as the SDF made gains in Raqqa, Dillon said Islamic State fighters still remained in the middle Euphrates River valley. Islamic State has lost much of its territory in Syria and Iraq this year, including its most prized possession, Mosul. In Syria, it has been forced back into a strip of the Euphrates valley and surrounding desert.
