Possibility of cross border tunnels

In no case should Pakistani trained terrorists succeed entering into Indian land from any side in the process of which the security forces are required to remain much ahead of the terrorists. Any breach in security and that too along Jammu border at vulnerable Vijaypur -Samba sector must become a cause of concern to the security apparatus in the UT. How did the Pakistan sent Fidayeen succeed in reaching Sunjuwan area of Jammu and engage our security forces into a five hour long encounter on April 22 close on the scheduled visit of the Prime Minister to Samba in Jammu, must be baffling the police / security authorities etc who are now not ruling out the possibility of some cross border tunnels existing through which these terrorists might have succeeded to gain entry into Jammu . The actual place wherefrom a little distance which they are believed to have trekked to board a waiting truck, is Daig Nallah along the border near Samba. The fact that Samba area has been found somehow ”breach- able” somewhere by the Pakistan backed and armed militants needs to be looked into which the BSF is otherwise doing as a routine and even drones are pressed into the process.
Although both the suicide terrorist bombers were killed , yet the possibility of one or two more having sneaked in along with the killed infiltrators cannot be ruled out , the suspicion for which gains ground looking to planting of IED device in Sidhra Jammu which, thanks to the timely detection by the police forces , a major tragedy was averted. Within this week , it is the second attempt of terrorists to target Jammu areas and create disturbances and panic as the new satanic strategy adopted by elements from across the border . One grenade having been found in the house where the two suicide bombers were eliminated denote that while infiltrating, militants obviously cannot carry guns and ammunition for getting detected and there must be over ground workers who provide them the arsenal which probably they succeed in accessing prior to sneaking in of these Pakistani infiltrators. The security forces, the Army and the police must be working on various probabilities and theories to deal with the situation.
