A newly released video shows members of an al-Qaeda-affiliated insurgent group in Syria equipped with US-made weapons, Press TV reports.
The insurgents in uniform are reportedly based in the Jabal Turkmen mountains in northern Syria, along the Turkish border. They are shown carrying US M-16 rifles.
Another video also shows insurgents holding the Saudi flag in the eastern city of Deir al-Zour.
Damascus has repeatedly criticized the United States and its regional allies including Saudi Arabia, Qatar and Turkey, over funding and arming insurgents fighting the government forces.
Syria has been experiencing unrest since March 2011. Damascus says the turmoil, which has killed many people, including large numbers of security forces, is being orchestrated from outside the country.
