With the onset of winter plus the presence of around 60 terrorists on the other side of the 198-km-long Indo-Pak international border, the BSF has deployed more men and more electronic surveillance gadgets to foil intrusion bids. “While we remain alert 24×7 throughout the year, manpower has been increased and more electronic gadgets for surveillance are being used to foil any mischief from across the international border,” said RK Sharma, Inspector General, BSF (Jammu Frontier).On the gaps in the form of rivers and rivulets that flow into Pakistan and marshy lands, he said they had been adequately covered.“That is why no infiltration bids are taking place. Till now, we have also not seen any suspicious movement on their (Pakistan’s) side but they (ultras) are very much present in launching pads. Perhaps our security grid is so strong that they are finding it difficult to attempt infiltration,” said Sharma.It may be stated here that during winter Pakistani terrorists shift their focus from the Line of Control to the international border, largely a plain area, to attempt intrusions and sneak into the state for carrying out terror attacks.On the international border, Pakistani militants usually adopt traditional routes that exist in the form of over 13 rivers and rivulets that flow into Pakistan.Chhap nullah, Bhag nullah, Tarnah nullah, Bain nullah, Aik nullah, Devak nullah, Basanter river, Tawi river, Chenab river and two or three rivulets that flow into Pakistan are being guarded by BSF men, said official sources. These gaps and marshy land are getting the attention of the BSF.“The BSF has put up more lights and obstacles, including early warning systems and laser fence, in some areas,” a source added. A second line of defence has also been put in place and all 15 commandants of the BSF have been asked to remain alert, said sources, adding that foot patrols have also been upped.
