Three other militants and a jawan sustained injuries in the gun battle, a senior police officer said.
Talking to PTI over phone, the officer said, "Police had inputs that a band of heavily armed militants were planning to ambush security forces in the area. The jawans of 4 Assam Regiment launched multiple search operations to neutralise the insurgents. A gun battle ensued between the troopers and the militants, resulting in three deaths".
The insurgents belonged to CorCoM, a conglomerate of six militant outfits, he said, adding that a rifle and three unexploded IED bombs were seized from them.
One of them succumbed in the hospital, he said.
The entire area of the encounter has been cordoned off with security forces still carrying out search operations, he added.
