All YPG forces, which constitute the majority of the SDF, must withdraw from the buffer zone entirely, along with their weapons, within 150 hours from the announcement of the deal. Their withdrawal would be overseen by Russian Military Police and the Syrian Border Guards, which would enter the zone at noon on 23 October. The YPG would also withdraw from the cities of Manbij and Tell Rifaat.[lower-alpha 4] Following the YPG withdrawal, joint Russian-Turkish ground patrols would be held in the buffer zone area, but only within 10 kilometres (6.2 mi) from the border and not including Qamishli.[lower-alpha 5][lower-alpha 6] Turkey would retain sole control of the areas it had captured during its offensive between the towns of Tell Abyad and Ras al-Ayn.
