"The Syrian Democratic Forces took under its control the Al Oukairishi settlement 15 kilometers [9 miles] to the southwest from the city of Raqqa," the source said.
Raqqa has remained under Daesh control since 2013, and is considered the de facto capital of the terrorist group.
In 2016, the US-led coalition announced the start of the operation to liberate the city. The Syrian Democratic Forces have been fighting on Raqqa’s outskirts for several months.
On Sunday, the Iraqi armed forces retook another terrorist-captured city, Mosul in northern Iraq, where the creation of Daesh was first declared in 2014.
