Saudi Arabia is constructing a 965-km high-tech "great wall" - a security barrier consisting of a sand berm and two chainlink fences topped by razor wire - along its border with Iraq to separate itself from the Islamic State (IS), said a report.  

The “Northern Border Security Project” will be Saudi Arabia's Maginot Line ( a line of concrete fortifications, obstacles and weapons installations that France constructed on the orders of Minister of War André Maginot just before the borders with Switzerland and Germany and Luxembourg during the run-up to World War II).
 
"The Wall" will have five layers of fencing, some of which 125 feet long, and a ditch to separate the country from Iraq to the north. The fences will be 100m apart with a third concertina fence in the gap between them, reported The Telegraph.

Saudi Arabia is also looking at doing the same thing with the country's 1,000-mile southern border with Yemen, it added.

An intruder alarm system will be provided by underground movement sensors, and 40 watchtowers equipped with night vision, thermal imaging cameras and radar supplied by Airbus industries. These Spexer 2000 radars can detect a truck 36 km away, and a pedestrian from a distance of 18km, stated the report.  

To co-ordinate the information from the sensors, there will be seven command-and-control centres and 38 communications towers connected by a 1,450km long fibre-optic network to each other and the Ministry of the Interior in Riyadh.

And to provide the response force, there will be 240 armoured cars backed up by helicopter gunships that will use a specially constructed patrol road running parallel with the fence.

The kingdom is also building a barrier across its frontier with Yemen. This barrier, which will may eventually stretch for 1,000km is intended to protect it from instability on its southern flank, the report added.
