The great wall of Saudi Arabia to guard from ISIS 

Saudi Arabia, the oil-rich territory is building a 600-mile barrier from Jordan to Kuwait to fortify the northern frontier from invasion by the Islamic State insurgency.

In response to the threat of an invasion by ISIS, the Saudi royal family, fenced and ditch six-mile-deep barrier, punctuated with radar surveillance towers systems that can detect individuals at up to 12 miles away and vehicles at up to 24 miles away, command centres and posts Border Guards with the orders to shoot anybody who tries to cross into Saudi territory illegally.
The multi-layered barrier includes 78 monitoring towers, 32 rapid-response centres, 10 mobile surveillance vehicles, eight command centres and three rapid intervention squads.
The first phase of the border security project was inaugurated in September by Saudi Arabia's King Abdullah bin Abdulaziz al-Saud almost immediately after Islamic State's Sunni insurgency swept across Iraq.
