"We have also strengthened our guards on the border, intensified patrol and are keeping a close vigil along the international border so that no one can sneak into our territory for sabotage," BSF IG SK Dutta, who is in-charge of Tripura, Mizoram and Cachar, told reporters in Agartala yesterday.

The BSF and its Bangladesh counterpart Bangladesh Rifles (BDR) have been conducting coordinated patrolling along the Tripura, Mizoram and Cachar borders for the last four months, he said.

"The BSF will now launch coordinated operations on the border along with other security agencies," he said.

"Now we will share our intelligence inputs with officer-in-charge of any police station near the border and also with other security agencies and then simultaneously launch operations which would be an effective step towards making the border foolproof," the IG said.
