Infiltration from India’s border with Bangladesh has become a key component of Bharatiya Janata Party’s strategy for state assembly elections.

Indian Home Minister Rajnath Singh yesterday inaugurated an advanced electronic surveillance “smart fencing” system along a geographically-tough 61-km stretch of Assam's border with Bangladesh to tackle cross-border crimes and provide respite to BSF personnel from round-the-clock patrolling.

Only those who came to Assam from Bangladesh immediately before the commencement of the Citizenship (Amendment) Act, 1985, -- and are not Indian citizens -- can be referred to the foreigners tribunals, Indian home ministry said yesterday.

India will launch a digital smart fencing project along Assam state's border with Bangladesh in November, Home Minister Rajnath Singh has said.
