Within days of an ominous warning by the country's top security adviser about terrorists infiltrating the armed forces, two soldiers have been picked up in Kashmir for possible links with the Lashkar-e-Taiba (LeT). In the first such case in 17 years of terrorism in the Kashmir Valley, two policemen were also taken in by intelligence officials, besides the two J&K Light Infantry men. Last week, TOI made public a letter by national security adviser M K Narayanan warning the states that terrorists could have found a way into the Air Force. Military Intelligence officers picked up the soldiers - identified as Lance Naik Mohammad Shakeel and Sepoy Abdul Haq - to interrogate them about alleged links with a LeT field commander responsible for organising attacks in the border districts of Poonch and Rajouri. The arrested policemen - Sikander and Kabir - were picked up after a LeT module was busted at Mendhar in Poonch district. Police sources said they had been working for LeT for the past three years. The depth of their involvement is being probed. Military sources said jawans Shakeel and Haq, who are from Gursai village in Mendhar tehsil in Poonch district, were taken into custody on Saturday following a tip-off that they had been contacted by Pakistani national Abu Osama, who is LeT's divisional commander for the Jammu region.
