All Tripura Tiger Force

The All Tripura Tiger Force (ATTF) was a Tripuri nationalist militant group active in India's Tripura State. It was founded on 11 July 1990, by a group of former Tripura National Volunteer members under the leadership of Ranjit Debbarma. The ATTF is considered a terrorist organisation by India. According to the South Asian Terrorism Portal, approximately 90% of the ATTF's administration are Hindu and the rest are Christians. The group was said to have been formed as the armed wing of the National Liberation Front of Tripura (NLFT) but split into its own organization. The group was headquartered in Tarabon in Bangladesh.
