The Assam police killed a hardcore militant of the banned United Liberation Front of Assam and arrested another militant in two separate operations in eastern Assam on Tuesday.
The police informed that a ULFA militant identified as Nitul Gogoi was killed following an encounter at Borbeel in Jokai area in Tinsukia district of Assam.
The police recovered a UMG gun and 22 rounds of ammunition from the slain militant.
In a separate operation police arrested another ULFA militant from Namrup area of adjoining Dibrugarh district.
Meanwhile, security forces acting on a tip-off dug out explosives kept inside a LPG cylinder from near Assam-Arunachal boundary at Missamari in Sonitpur district of north Assam on Tuesday.
The explosives were suspected to be stored under the ground by militants belonging to the banned National Democratic Front of Bodoland.
The police and army have intensified operations in the wake of intelligence inputs about NDFB's plan to carry out series of explosions in the state.
Forces are also keeping a close watch on movements of ULFA militants, as the efforts to initiate talks with the outfit has failed to bear fruit so far.
The ULFA is carrying out a well-coordinated and widespread extortion drive in eastern Assam areas.
