Notwithstanding the repeated demands from India [ Images ] for dismantling terror infrastructure in Bangladesh, it still remains a major hub for the ultras with as many as 172 insurgent camps operating in that country.

"Bangladesh is taking some action against them. They have launched a few operations in which some militants have been killed. But it is not enough, Dhaka needs to do more," outgoing BSF Director General R S Mooshahary told PTI in an interview.

"We have given them a list of 172 insurgent camps. They verified it and they say they are not there, which I feel is a routine reply," he said adding, "We are sure there are camps and we are sure that some insurgents from India have taken shelter in Bangladesh."

Expressing concern over the continued movement of people across the India-Bangladesh border despite intensive checking, the Director General was also of the view that the government should shift its focus from the western to the eastern sector.
