Officially, ALRUKBAN REFUGEE CAMP, is located in a demilitarized zone. However, the pilot of the Jordanian military helicopter used during a recent NBC News visit wouldn’t fly over it for fear of being shot down by ISIS cells in the camp.
Brig. Gen. Sami Kafawin, commander of Jordan’s army in the area, told NBC News that militants there “have whole weapons systems … small arms, RPGs, anti-aircraft.”
He added: “They consider the camp a safe haven. We consider it an imminent threat.”
