Israeli security officials have recommended building a barrier along the border with Jordan -- the Jewish state's only frontier that does **t yet feature a fence. "Security officials recommended the construction of a security barrier to protect the new airport which will be built at Timna" some 20 kilometres (12 miles) **rth of resort city Eilat, an army spokeswoman said, without elaborating. Work has already begun on the new airport near Eilat, which lies across the Jordanian border from the port city of Aqaba. Newspaper Haaretz reported that the planned 30-kilometre (19-mile) barrier was designed both to protect the airport and to foil attempts by would-be "jihadist infiltrators" from Jordan, which is home to some extremist sympathisers and a number of radical clerics.
