Home minister Rajnath Singh yesterday said the NDA government wants to completely seal the Indo-Bangladesh border as illegal immigration was a matter of serious concern, reports PTI from New Delhi. "We want to take all possible steps to check illegal immigration. All loopholes have to be plugged," he said. The home chief also said that he will soon visit the border areas to personally see the situation along the forward lines as illegal immigration from the neighbouring country continues to be a major concern. "I will visit the Indo-Bangladesh border soon, probably within this month. I want to see the situation along the border as we are committed to check illegal immigration," he said at a seminar organised by the All Assam Students Union. The seminar - '30 years of Assam Accord: Issues, challenges and implementation' - was organised on the eve of the three decades of the signing of the pact which was aimed at detection and deportation of illegal immigrants from Assam, by AASU and the central government on August 15, 1985.
