The United States has transported arms and logistic equipment from Iraq to Syria's Al Hasakah Governorate, SANA reported citing local sources in Rmelan al-Basha village.
According to the media outlet, the convoy included 59 refrigerator trucks, tankers with military supplies and Humvees.
The convoy travelled to Kharab al-Jeer where the US forces are stationed, SANA said. The military entered the country from northern Iraq, accompanied by the US-backed Syrian Democratic Forces' vehicles, it added.
Syria has been embroiled in a military conflict since March 2011 and drawn in various outside combatants, including the United States.
Syrian President Bashar al-Assad has repeatedly condemned the US presence in the country which he views as illegal as it was not mandated by either Damascus or the United Nations.
