At least 11 persons, including a woman and a child, were injured in a blast allegedly triggered by ULFA militants in Tinsukia town in upper Assam yesterday night, the police said.

 

A hand grenade kept in a dustbin exploded at Debipukhuri Pachali area in the centre of the town with a deafening sound at 7.30 PM, Tinsukia district SP Mukdhajyoti Mahanta said.

 

The injured were admitted to Tinsukia Civil Hospital from where four seriously injured were sent to the Assam Medical College Hospital in neighbouring Dibrugarh district, Mahanta said.

 

The area was cordoned off and investigations are on.

 

Early in the morning, a hand grenade exploded at Duliajan near here adjacent to a CRPF camp but no one was injured.

 

Who carried out the explosions was yet to be ascertained, police said, adding ULFA militants from outside the district were suspected to have been behind it.

 

A hardcore ULFA militant, self-styled Sergeant Major Rongmon Asom alias Mecuri, was killed in an encounter with the army in Tinsukia district on 27 April.
