An ULFA militant was killed and an army personnel injured in an encounter in Assam's Darrang district on Tuesday, police said.
Acting on a tip-off that five ULFA militants had taken shelter in a house at Kalitapara village of the district, a joint team of the army and police launched an operation in the area this afternoon.
A heavy exchange of fire, lasting for more than 45 minutes, took place between the militants and security forces in which the militant was killed and a security personnel seriously injured.
The four other militants managed to escape and a search operation was launched to apprehend them.
The security forces recovered a pistol from the slain militant, the police added.
