Operation Roukhala was an ethnic cleansing operation launched by the All Tripura Tiger Force (ATTF) for the eviction of Bengali Hindus from Tripura in the late 1990s and early 2000s. The word Roukhala in Kokborok literally means ouster or deportation or driving out. In the early stages of the movement, the ATTF and the National Liberation Front of Tripura (NLFT) separately issued quit notices to the Bengali Hindus. The ATTF named it as Operation Roukhala. Later NLFT joined the movement. According to the political leaders in Tripura, the rebels resort to abduction and murder of non-tribals in the Tripura Tribal Areas Autonomous District Council (TTAADC) area as a part of Operation Roukhala.
