The blast occurred on a railway track near Halflong station and a goods train was derailed following the blast. Halflong is the only hill station of Assam.
However, no casualties have been reported yet.
The blast ahead of the Republic Day created tension and panic among citizens. Police officials informed that security in the whole state has been beefed up.
On the other side, citing several encounters of ULFA militants, terror-outfits threatened the Assam government to boycott the Republic Day and threatened to strike in the state.
The tense situation can destroy the ongoing peace process which raised a ray of hope for the nation as for the first time ULFA leaders agreed for the peace talk process without any condition.
