ANKARA, Sept. 22 (Xinhua) -- The 828-kilometer-long security wall along Turkish-Syrian border is expected to finish construction by the end of September, state-run Anadolu Agency reported on Friday.
A total of 731 km of the border wall has already been built, and the remaining 97 km would be completed by the end of this month, an anonymous Turkish official was cited as saying.
The wall includes physical, electronic and advanced technological layers. The two-meter-wide and three-meter-high physical layer is mainly made up of modular concrete blocks, topped with one-meter-high razor wire. It also includes patrol routes, passenger tracks and watchtower.
The electronic layer consists of close-up surveillance systems, thermal cameras, land surveillance radar, remote-controlled weapons systems, command-and-control centers, line-length imaging systems and seismic and acoustic sensors.
The advanced technological layer includes wide area surveillance, laser destructive fiber-optic detection, surveillance radar for drone detection, jammers and sensor-triggered short distance lighting systems.
