The army and Assam Police gunned down three top NDFB(S) militants in Kokrajhar district on Sunday.
On specific intelligence inputs on movement of hardcore NDFB(S) militants, the army challenged suspected individuals who were moving through dense jungles in the early hours of Sunday.
After coming under “heavy non-discriminatory fire”, the joint team retaliated with controlled fire and killed the three hardcore NDFB(S) militants, the officials said.
Two of them have been identified as Rahul Basumatary and Ritu Basumatary, officials said.
Four pistols, a large quantity of ammunition, hand grenades have been recovered from the slain militants.
Officials claimed that the surgical operation which was carried out under torrential rains, in thick foliage and undergrowth of the Assam jungles, is a major setback to the NDFB(S), which has been active in the area.
