The United States has shored up its presence in Syria, transferring about 150 trucks and armoured vehicles and mobile generators to northeast Syria from neighbouring Iraq, Turkey’s Anadolu Agency has reported, citing local sources.

According to Anadolu’s sources, the vehicles made their way into Kurdish-controlled areas of northeast Syria on Monday night, crossing the Simelka checkpoint along the Syrian-Iraqi border, and arriving at a US Armed Forces logistics center in Syria’s Kharab Ishq and Sirrin on Tuesday.

Unconfirmed video footage of the transfer of the vehicles has been published on social media.

“The US is continuing to assist the separatist terrorist PKK organisation in northern Syria. Video of the latest convoy sent. No camouflage. They’re out in the open now.”

The video shows generators and construction equipment, Humvees, and Toyota pickup trucks carried by transport trucks.

President Donald Trump announced plans to withdraw the contingent of 2,000 US troops from Syria in December, citing the imminent defeat of Daesh (ISIS)* and his campaign promise to bring the US home from “endless wars” in the Middle East.

Earlier Tuesday, Turkish President Recep Tayyip Erdogan said that no satisfactory arrangement had been made with Washington on the creation of a safe zone in northern Syria, and warned that Turkish patience was running out.

Erdogan stressed that if Kurdish YPG militia, which Ankara considers terrorists, were not removed from Syria’s Manbij in a two weeks’ time, Turkey would “take steps to eliminate the threats to national security.”

Last month, commenting on US-Turkish negotiations surrounding a proposed 30-kilometer’ buffer zone’ in Syria between Turkish and Kurdish forces, Russian Foreign Minister Sergei Lavrov said that any agreement involving Syrian territory must include an agreement from Damascus.

Damascus has rejected the safe zone idea, accusing Ankara of turning “a blind eye to the international resolutions which have always affirmed respect for Syrian territorial integrity.”
