Since the 1990s, there is an ongoing irredentist Tripura rebellion, involving militant outfits such as the National Liberation Front of Tripura and the All Tripura Tiger Force (ATTF); terrorist incidents incidents involving the ATTF claimed a recorded number of 389 victims in the seven-year period of 1993 to 2000.
The Armed Forces (Special Powers) Act, 1958 (AFSPA) was first enforced in Tripura on 16 February 1997 when terrorism was at its peak in the state.
Ever since it was enforced in Tripura, the Act, as per its provisions, was reviewed and extended after every six months. However, in view of the improvement in the situation and fewer terrorist activities being reported, the Tripura government in June 2013 reduced operational areas of the AFSPA to 30 police station areas.
The last six-month extension to AFSPA was given in November 2014, and after about 18 years of operation, it was repealed on 29 May 2015.
