Jordanian Chairman of the Joint Chiefs of Staff Mahmoud Freihat warned in an interivew with BBC on Saturday that ISIS fighters have anti-aircraft missiles.
In the interview, which was given in Arabic, Freihat referred specifically to the Syria-Jordan-Israel border, near the Golan Heights area.
"This faction is a constant and close threat to Jordan. Some of the areas its fighters are in are a kilometer away from the border," he said."They have tanks, armored vehicles, anti-aircraft missiles and machineguns that can hit the military posts on the frontline."
In truth, the ISIS was reported to have seized Russian anti-aircraft missiles a few weeks ago, when they recaptured th Syrian town of Palmyra, and they are not the first terrorist group to have anti-aircraft abilities.
The US Congress also may have contributed, by allowing the US to sell anti-aircraft missiles to Syrian rebel groups, despite the high risk they would fall into ISIS' hands.
