The US and its coalition allies have vacated three major military sites located in the middle Euphrates River Valley.
These include Green Village Mission Support Site, H2 Base, and Euphrates Mission Support Site — also known as the Conoco Gas Field.
According to the report, the infrastructure of these bases was either dismantled or handed over to the so-called Syrian Democratic Forces (SDF), a US-backed group operating in the region.
Troops previously stationed at these locations were either redeployed to other US bases in Iraq and Syria or returned home after completing their missions.
The report did not specify the number of personnel withdrawn.
This drawdown is part of a broader Pentagon strategy announced earlier this year to consolidate its military footprint in Syria.
Under this plan, the US aims to reduce its presence to a single base and fewer than 1,000 troops.
Washington has maintained a military presence in Syria and Iraq since 2014 under Operation Inherent Resolve, which it claims is aimed at countering the spread of Daesh (ISIS or ISIL) terrorists.
However, experts have widely challenged this justification, viewing the continued occupation as a destabilizing factor in the region.
