As reported by Reuters news agency, the U.S.-backed Syrian Democratic Forces (SDF) deployed around a thousand additional fighters to the front lines with the Islamic State in Raqqa on Sunday. The fighters were sent to the east and west of the city. The SDF launched its U.S.-backed assault to capture Raqqa last month. The SDF media office said in a statement, that they had “completed their training in SDF camps in cooperation with the coalition forces, with the aim of supporting the campaign and achieving new progress.”
The Syrian Observatory for Human Rights, a UK-based organization that reports on the war, said the SDF had made advances on Sunday in the south of the city, and had also retaken ground lost in an Islamic State counterattack on Friday.
