The ULFA is a separatist outfit operating in Assam for the indigenous Assamese and seeks to establish a sovereign Assam with an armed struggle in the Assam conflict.
In 1990, the government of India banned ULFA, citing it as a terrorist organisation.
The organisation is known for a number of assassinations and bombings, and also reportedly maintains a number of camps in Bangladesh, where members are trained and sheltered away from Indian security forces.
While, the PLA of Manipur founded by N. Bisheshwar Singh in 1978, is a separatist armed revolutionary group fighting for a separate independent socialist state of Manipur.
