Syrian Arab Army (SAA) forces entered a recently abandoned US military base near Manbij in northern Syria on Tuesday.
The base, which appears to have been left speedily by withdrawing US troops includes still erected tents, some with forgotten or abandoned equipment left within.
The US base was reportedly built after the area had been cleared of Islamic State (IS; formerly ISIL) militants.
Footage from Monday showed US Army forces passing in the opposite direction to SAA troops on the road linking Manbij to Kobani.
The SAA and the SDF struck a deal on Sunday that has resulted in SAA forces deploying to the area in order to defend against the ongoing Turkish military operation.
On October 9, Turkish President Recep Tayyip Erdogan announced the beginning of a military operation in north-eastern Syria dubbed 'Operation Peace Spring'. Ankara says the aim of the Turkish offensive is to create a 'safe zone' cleared of Kurdish groups.
