At least three militants were reported killed in a gunfight with Assam Rifles at the highly porous India-Myanmar border on Saturday.
The encounter took place 7km north of Manipur's border town of Moreh. The killed militants were yet to be identified.
More details awaited.
In July, the security forces had killed seven suspected militants of the National Socialist Council of Nagaland–Khaplang (NSCN-K) in Nagaland.
