"In the name of the General Command of the Euphrates Operations Command, we now announce the beginning of the fourth phase to clear the remaining northern countryside and the valley of Jalab from the terrorists and to remove the last obstacles in front of us, to prepare for the liberation of the city of Al-Raqqa," the SDF said in a statement.
