As part of the US-Turkey deal to establish a buffer zone at the border between Syria and Turkey, the Kurdish YPG has begun the process of withdrawing all of its forces from the border region, starting near Tel Abyad and Ras al-Ayn.
Fighters and heavy arms are being pulled back from the zone, defensive
earthen fortifications were demolished, and border posts were being
handed to local forces that will still be operating in the area.
The US and Turkey made the deal to try to prevent Turkey from invading
Kurdish-held territory across northeastern Syria. US and Turkish forces
will jointly manage the border area.
All the Kurdish forces are intended to withdraw to areas between 5 and
14 km from the border. The YPG and Turkey are still at odds, and while
the safe zone will temporarily prevent a confrontation, they are likely
to remain hostile toward one another.
