Saudi–Iraq barrier

The Saudi–Iraq barrier is a fortified border barrier built by Saudi Arabia along its border with Iraq. The barrier was proposed in 2006, and was constructed in 2014 following the rise of the Islamic State of Iraq and the Levant in Iraq. The barrier is sometimes referred to as the Great Wall of Saudi Arabia.

History
In April 2006, while Iraq was experiencing a high level of sectarian violence, Saudi Arabia began to call for tenders to construct a border barrier in the form of a fence along the border in an attempt to prevent the violence in Iraq spilling over into Saudi Arabia.

The proposed fence would run for approximately 900 km along Saudi Arabia's isolated northern desert border with Iraq. It was part of a larger package of fence-building to secure all of the Kingdom of Saudi Arabia's 6,500 kilometers of border. It would supplement the existing 7-meter-high sand berm that runs along the border, in front of which there is an 8-kilometer stretch of no-mans-land which is regularly swept smooth so that trespassers can be tracked.

The proposals were not implemented until September 2014, when the Iraq War had escalated following the rise of the Islamic State of Iraq and the Levant. ISIL's occupation of much of western Iraq had given it a substantial land border with Saudi Arabia to the south, and the barrier is intended to keep ISIL militants from entering Saudi Arabia.

The line consists of a multi-layered fence and ditch barrier wall, stretching from Turaif near the Jordanian border to Hafar Al-Batin near the Kuwaiti border. The border zone includes five layers of fencing with includes 78 monitoring watch towers, night-vision cameras, and radar cameras, eight command centres, 10 mobile surveillance vehicles, 32 rapid-response centres, and three rapid intervention squads.
