Besides,round the clock vigil,thermal imagers and battle field surveillance radars are being used along the three-tier barbed wire fencing along the border. The troops have also mapped the infiltration routes in borderline Pirpanchal ranges,vallies,thick forests and riverine areas. We have taken enough measures to foil militantss plan to sabotage the I-day functions and cause bloodshed and violence, a police officer manning the border division said.
