Islamic State has recently found a following among Bedouin tribes in southern Jordan, tens of kilometers away from the border with Israel, sources from the IDF's Southern Command claim, according to Walla! News. Sympathy for the terror organization, IDF sources fear, may spur terror cells to be established along the border, from where terrorists will infiltrate into Israel's Aravah region and carry out attacks. Concern is only amplified by the fact that there is no border fence between Jordan and Israel in that region, and the Aravah Division of the IDF, responsible for border security, suffers from low manpower.
