The BSF have found out the dead end of the 300-mt long secret tunnel from Pakistan into Indian into Indian territory -- discovered along the international border in Samba district on June 28.
However, it has still to be corroborated by the team Geological Survey of India(GSI) which is also carrying out digging in its own way.
"The dead end of the tunnel was found 20-mt ahead in a straight line from the point where it was detected. It didn't have any opening. However, till GSI also makes the same statement it can't be said with certainty that it's last point of the tunnel," IG(officiating) BSF NS Jamwal told HT.
The Border Security Force (BSF) had been using excavators for digging.
The GSI team had meanwhile send requisition for more sophisticated tools for excavation.
The team had on Tuesday during its operation had found three water bottles.
The tunnel, which could have enabled infiltrators to crawl 300 m into the Indian territory, was accidentally discovered by a farmer after parts of it caved in following rains. The man saw the cave-ins, which ran along a straight line, on his fields near the Chachwal border outpost of the BSF.
"Since the tunnel didn't have any opening it appears that Pakistan had either given up the plan or was buying time to further start operation, which requires meticulous planning and professionals," said a BSF official.
Pakistan had fired at Border out Post along International Border and also at LoC after the detection of the tunnel in which two BSF personnel were injured in Hirangar sector.
India had last Sunday lodged protest with Pakistan over the detection of the tunnel.
