Guwahati: At least six persons were injured by unidentified persons claiming to be ULFA in Tinsukia district, officials said on Thursday.
The assailants armed with sophisticated sharp weapons attacked people at Jagun along the Assam-Bangladesh border and injured six of them seriously on Wednesday night.
They left the spot after claiming themselves to be ULFA cadres, they said.
The army and police have launched massive operation to track them out, they said.
Meanwhile, anti-talk hardline ULFA Paresh Baruah faction on Thursday warned that "Indians residing in Assam will have to face the effect of the colonial force's operations on the indigenous people".
In an e-mail to the media, the outfit's 'publicity secretary' Arunudoy Dehotia said, "the ULFA condemns the operations launched by the army's Cobra Commando against the indigenous people".
