Union Home Minister Rajnath Singh today asked five eastern states sharing boundaries with Bangladesh to be extra vigilant against influx of Rohingyas and illegal immigrants through the porous Indo-Bangla border.<br/><br/>At a meeting of chief ministers and home ministers of West Bengal, Assam, Mizoram, Meghalaya and Tripura in Kolkata, Mr Singh said, a border protection grid on the lines of Unified Command set up in insurgency-hit states will soon come up in these states to check illegal infiltration. He said, the concept of the grid has been planned as a multi-pronged and foolproof mechanism to secure the Indo-Bangla border. <br/><br/>The Home Minister said, NDA government has been giving highest priority to secure India's international border by putting in place a robust system to facilitate legitimate trade and commerce. He said, radical elements and terrorists can only be checked with joint action and active cooperation of central and state governments.<br/><br/>Assam Chief Minister Sarbananda Sonowal sought a new law to check the cross border smuggling, including cattle, and effective steps to end illegal immigration. He said, the central government should set a deadline to completely seal the international border with Bangladesh.<br/><br/>West Bengal Chief Minister Mamata Banerjee appreciated the central government's initiative to hold this meeting of the chief ministers and offered full cooperation to any joint action.
