For now it seems US troops are not only maintaining their bases in the northeast, where Syria's oil and gas fields are located, but are actually expanding the Pentagon presence, and very close to the border with Turkey.

On Thursday the London-based Syrian Observatory for Human Rights (SOHR), which has long been known as an anti-Assad opposition outlet in exile, said that US forces are making preparations to establish a new military base in the northern city of Ain Al-Arab, or Kobani.

The outlet cited its observers on the ground who say US forces brought in a convoy of 50 trucks carrying cement blocks to areas of northeast Syria controlled by the US proxy Syrian Democratic Forces (SDF, a group largely dominated by Syrian Kurds).

Ain Al-Arab is a district of Aleppo province in northern Syria. The area around Aleppo saw sporadic fighting between Syrian Kurds and HTS jihadists throughout December.

"SOHR activists have reported seeing the convoy on Al-Hasakah-Al-Raqqah highway, while it was heading to Ain Al-Arab area (Kobani) in the eastern countryside of Aleppo," the report described, and noted that a SDF military vehicle was providing escort.

"According to SOHR sources, this comes as a part of US forces' efforts to boost their bases and establish a new military base in Ain Al-Arab in light of the growing security and military tension in that region." Russia's Sputnik is also reporting the development.

The SOHR report provided additional details strongly suggesting a new US military base on this border region near Turkey:

Yesterday, SOHR sources reported that "International Coalition" forces brought a convoy of logistic reinforcements including premade chambers, surveillance cameras, cement blocks, fuel tanks and digging machineries towards Ain Al-Arab (Kobani).

According to reliable SOHR sources, the digging and drilling will start tomorrow and more military reinforcements such as soldiers, weapons, armored vehicles, radars and anti-aircraft weapons will be brought.
