Around four million residents of the north Indian state of Assam are at risk of losing their citizenship.

The Assamese government published a register of citizens which required people to prove they came to India before March 24th, 1971, two days before Bangladesh’s declaration of independence.

The Hindu-nationalist Bharatiya Janata Party plans to remove those deemed foreigners from Assam, though local government assure those recently designated foreigners will not be immediately deported.
