BSF Inspector General P K Misra informed on Tuesday that the dossier of evidences given to the Assam's counter-insurgency unified command by various intelligence agencies of militants attacking Assam after infiltrating from Bangladesh is being collated by the union government.

Misra told reporters that New Delhi will demand action against the "outlawed outfits" using Bangladesh as their base to carry out terrorists attacks in India as India had demanded from Pakistan after the Mumbai terror attacks. He said: "The government of India would be submitting a report to the Bangladesh government soon."

Mishra said: "BSF and sister security agencies are meeting regularly and sharing intelligence inputs and passing the same to the field level each day."

He, however, admitted of possible "lapses" of security agencies in stopping terror attacks.

As the BSF guards 577 kilometres of international border with Bangladesh in Assam-Meghalaya sector Misra said: "The eastern sector is problem-oriented as it is more porous with difficult hilly terrain." He felt guarding the eastern sector was "most challenging."
