Srivastava said the BDR is trying to ascertain the presence of these insurgents on their side of the border which is a difficult task in absence of any specific input.
"DG BDR is trying to see whether these people are there. They may or may not be there, we do not know unless there is a specific input that so and so is there in this building, in this locality, in this city. Even then he may be there, he may not be there. We have made our concerns clear. We have got a very positive response from them," he said.
Chief of BDR Major General Mainul Islam, who is leading a 19-member delegation, also assured that territory of Bangladesh will not be used for terrorist activities against any country.
