Syrian Arab Army (SAA) units returned to border areas in the countryside east of Qamishli on Tuesday, with the troops seen on the road between Kahtanieh and Tal Jhan.
Lorries and pickup trucks carrying troops and bearing the Syrian flag were filmed driving along roads in the northeastern region.
Government forces are returning to the area as part of an agreement with the Syrian Democratic Forces... Еще (SDF), composed primarily of Kurdish militia and led by the People's Protection Units (YPG).
The SDF agreed to share the control over the area with SAA after US forces retreated allowing Turkey to launch a military operation.
With Turkey, Russia and Syria now carrying out joint patrols in the so-called 'safe-zone', the YPG has since been forced to retreat.
