Saudi Arabia: Sandwiched by Jihadists in Iraq and Yemen

Saudi Arabia believes it may be next in the Isis firing line

BBC: Along Saudi Arabia's long, lonely desert border with its northern neighbour Iraq, the Ministry of Interior guards have every reason to stay alert.

Isis, the well-armed and well-funded jihadist army that has seized control of most of western Iraq, is now effectively at the kingdom's doorstep.

Nearly half the 900km (560 mile) Saudi-Iraq border is with Iraq's Anbar province where The Islamic State in Iraq and the Levant (Isis), now rebranded as simply "The Islamic State", is largely able to move its fighters around at will.

Saudi Arabia may not yet be directly in its sights but officials fear this is only a matter of time.

Isis backlash

Many of its most violent frontline fighters are believed to be Saudi nationals who may eventually come home, radicalised and brutalised by the conflict.

King Abdullah has ordered "all necessary measures to secure the kingdom from terrorist groups or others who might disturb the security of the homeland". » | Frank Gardner | BBC security correspondent | Wednesday, July 02, 2014
