The Bru National Liberation Front (BNLF) is an armed outfit of the Reangs and is currently engaged in negotiations with Mizoram government. The BNLF formed in 1996 following violent clashes between ethnic Mizos and Reang tribesmen in the Mamith sub-division of Mizoram state. The immediate cause of the conflict was the demand for an Autonomous District Council (ADC) by the Bru National Union (BNU).

The Reang Democratic Convention Party (RDCP), another Reang organisation, passed a resolution in this regard. This reportedly provoked Mizo organisations like Mizo Zirlai Pawl (MZP) and Young Mizo Association (YMA) — fearing geographical division of Mizoram — to organise violent attacks, in October 1997, on Reang settlements.

The outfit's cadre strength is estimated to be around 100, and proclaims its primary objective as the protection of rights and dignity of Reangs. BNLF also endeavours to protect the religious identity of Reangs, which it claims to be Hinduism. This is manifested in its vehement opposition to the alleged imposition of Christianity on Reangs. It has also demanded a separate Reang homeland in Mizoram. Subsequently, it transformed its stand and aimed to achieve a separate ADC, and reservation in the Mizoram Legislative Assembly for the community. Besides, it has also taken up with the Mizoram government the issue of repatriation of Reang refugees who had been displaced during the October 1997 ethnic clashes. Only recently, it has agreed to tone down its demand for an ADC and settle for a regional council.

Surajmani Reang and Hmunsiama are 'president' and 'deputy commander' respectively of the outfit. Both had managed to escape from the clutches of National Liberation Front of Twipra (NLFT) militants, who were holding them captive, in January 2001. Thang Masha is another important leader of the outfit. Other leaders of the outfit include A Joseph, 'advisor', Solomon Prophul, 'general secretary' and S Bru, the 'organising secretary'.

The BNLF suffered its worst reverse when the then 'general secretary', Hambai Mshoy, and the then 'army chief', Sheing Molshoy, were killed in a clash with the NLFT on July 9, 2000, at a camp in Bangladesh.

BNLF cadres are active in parts of Mizoram, Tripura and Assam. The areas where the outfit has carried out major attacks include the Mamit and Lunglei districts of Mizoram, Hailakandi district of Assam and Kanchanpur sub-division of North Tripura district. The BNLF is also known to be operating in the dense forests along the Mizoram-Tripura border. Besides, its hideouts are located in the Bhuban Hills of Cachar district in Assam.
