The US forces sent 40 truckloads of military gears into Syria from neighboring Iraq on Thursday, state news agency SANA reported.
The trucks, escorted by US military vehicles when they entered from an illegal crossing between Iraq and Syria, reached the "illegal" US bases in the countryside of the northeastern province of Hasakah.
Thousands of truckloads of US military gears have entered Syria through the illegal crossings on the Syria-Iraq border over the past months, said SANA.
Meanwhile, the Syrian Observatory for Human Rights also reported the entry of the US military gears into Syria on Thursday.
It said the shipment is the second to enter the war-torn country in August alone.
On Aug. 5, the US brought in 30 truckloads of logistic and military equipment from its bases in Iraq to the countryside of Hasakah.
