Manbij Military Council, a local component of largely YPG-led SDF, announced on Thursday that it had reached a deal with Syrian regime to create a buffer zone against Turkish-backed forces who held the territories in the west of Manbij.
"We have said that we would strike if the YPG fails to withdraw", Cavusoglu said, using the acronym of a prominent Syrian Kurdish militant group.
