The Russian-Turkish agreement signed Oct. 22 on the security and field situations south of the Turkish-Syrian border included an item stating that at noon on Oct. 23, Russian military police and Syrian border guards were to enter the Syrian side of the Syrian-Turkish border, outside the area of Operation Peace Spring, to facilitate the removal of the Syrian Democratic Forces (SDF) and their weapons to a depth of 30 kilometers (18 miles) from the Syrian-Turkish border.
The process needed to be completed within 150 hours, after which joint Turkish and Russian patrols would begin operating west and east of the area of Operation Peace Spring at a depth of 10 kilometers (6 miles), with the exception of the city of Qamishli due to the presence of the Syrian regime’s security forces there.
