Acting on intelligence inputs, a joint operation was launched by the Army and the police in the district yesterday where the militant was gunned down in an exchange of fire with the security forces, a defence spokesperson said.
Arms and ammunitions were seized from the encounter site, the spokesperson said.
The militant, Ramesh Bora, was the deputy of another hardcore ULFA(I) militant Rajan Deka and the self-styled 'area commander' of the outfit's Udalgudi and Darrang districts, he said.
