Killing of unarmed, innocent Bangladeshis by the BSF on our borders has increased in recent times. Despite repeated assurances by the Indian authorities to stop border killing, the situation has not improved. Such behaviour by BSF is unacceptable. Many high-level discussions have been held between the two countries, but with no results. We are seriously concerned about the security of our people. It is high time we sought the intervention of the UN to stop border killing once and for all.
