(IsraelNN.com) Four Arabs from the Judean Mountains area managed to enter the IAF's Nevatim Air Force Base Wednesday without tripping any alarms and without arousing suspicion. They seem to have been looking for work. The Arabs managed to pass multiple security rings monitored by closed circuit cameras and wandered about the base, passing near advanced jets, bombs and advanced weaponry and in clear sight of officers and soldiers who did not take special notice of them. Only after they approached a contractor for work was the base's command notified of their presence. The IDF says the incident will be investigated.
