"Smuggling of arms and cross-border movement of militants cannot be ruled out. The nature of border is very hostile and it is difficult to completely check the menace unless the fencing project is completed," BSF Inspector General (Assam and Meghalaya frontier) Prithvi Raj said.
The statement comes close on the heels of intelligence inputs indicating that the porous Meghalaya-Bangladesh border continues to be a major route for entry of militants from Bangladesh and transshipment of arms and explosives into India.
Revelations from a couple of top arrested militants had prompted the BSF to strengthen vigil along the border, particularly in the Garo hills belt of Meghalaya.
