Ten people were injured, four of them seriously, when suspected ULFA militants triggered two blasts in Kokrajhar and in Guwahati on Tuesday even as troops shot dead two members of the banned group.
In the first explosion, nine persons were injured as the IED fitted to a bicycle went off near Srirampur check-gate along the Assam-West Bengal border in Kokrajhar district at around 11.30 am.
Three of the injured are in serious condition, police said. Another bomb was also found from the site. Militants then exploded a bomb in front of a Railway Protection Force camp in Bamunimaidan area here this evening in which a youth was seriously injured.
Meanwhile, two bombs were recovered from a bus at Baihata Chariali in Kamrup district during routine checking. The stepped-up violence comes ahead of Republic Day for which ULFA and three other groups have given a boycott call.
On the other hand, two hardcore ULFA militants were killed in separate incidents. Six rebels of the group were also apprehended from different parts of the state.
The North East Frontier Railways has suspended the running of night trains in upper Assam from January 24 to January 27, a railway spokesman said.
