A dozen “laser walls” have been made operational along the India-Pakistan International Border (IB) in Punjab to plug the porous riverine and treacherous terrain and keep a vigil against intruders and terrorists exploiting the frontier areas to cross over.
While eight infra-red and laser beam intrusion detection systems are "up and working" along as many vulnerable and sensitive areas of the IB in Punjab, four more will be operationalised in the next few days, a senior BSF official said.
The "laser walls" or fence are being monitored by the Border Security Force (BSF).
The decision to install these laser walls was taken by BSF two years ago keeping in mind the vulnerability of the border in these areas as barbed wire fencing could not be installed in many infiltration prone areas due to treacherous terrain or marshy riverine topography.
After the Pathankot terror attack, where it was suspected that terrorists crossed over from Pakistan by breaching the IB from Bamiyal area in Punjab, Union Home Ministry and BSF have sped up the deployment and activation of these walls along the long and winding border.
