US-backed SDF: Battle for IS capital begins 'within days'
None
US-backed Syrian forces made new progress against Islamic State militants along the southern bank of the Euphrates River on Saturday as the coalition positions itself to launch a decisive bid for Raqqa, the de-facto capital of the militants' so-called "caliphate."
The Kurdish-led Syrian democratic Forces said they were in control of 90 percent of the town of Mansoura, approximately 26 kilometers (16 miles) southwest of Raqqa.
