The 'laser walls' are armed with night and fog operability tools

NEW DELHI: A dozen " laser walls " have been made operational along the India-Pakistan international border in Punjab to plug the porous riverine and treacherous terrain and keep an effective 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 international border (IB) in Punjab, four more will be operationalised in the next few days, a senior official of the Border Security Force (BSF) said.

The "laser walls" or fence are being monitored by the BSF which guards the Indo-Pak border in Jammu and Kashmir, Punjab, Rajasthan and Gujarat.

The decision to install these laser walls was taken by the 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 border from Bamiyal area in Punjab, Union home ministry and BSF sped up the deployment and activation of these walls along the long and winding border.

A total of 45 such laser walls will be installed in these areas along the international border in Punjab and Jammu, a blueprint prepared in this regard and accessed by PTI said.

According to the blueprint, the BSF along with a team of technical experts will be conducting a pilot project for deploying "technological solutions" for effective border guarding at two "sensitive" riverine stretches in Jammu sector which entails deployment of smart sensors to pick up suspected movements along the international border.

"The laser walls have started working and their functioning is being monitored. Preliminary results in detecting illegal movements are encouraging," the official said.

He said sensors were being monitored through a satellite-based signal command system and armed with night and fog operability tools.

Apart from these, four other pilot projects of similar kind in stretches of 30-40 kms of international border in Jammu and Gujarat and one in West Bengal along Indo-Bangla border have been approved by Home Ministry to secure Indian borders effectively.

"Work on them will begin by next month," he said.

After the Pathankot incident, BSF had deployed an additional battalion (about 1,000 men) in Punjab sector even as it has increased the number of its ambush operations and patrol in the area.

The BSF is also considering deploying at least four more battalions in Punjab and Jammu border areas as a second-tier of defence after withdrawing these units from the Line of Control
