One person was killed and at least six wounded, three of them critically, in a powerful grenade attack Friday in a crowded marketplace in Assam, officials said.
Police blamed the outlawed National Democratic Front of Bodoland (NDFB) for the attack.
A police spokesman said militants riding on a motorcycle lobbed a grenade at a crowded market at Udalguri town, about 90 km north of Assam's main city of Guwahati.
The incident occurred around 6.45 p.m.
"A group of people were sitting by a fire close to the market when the grenade attack took place," a senior police official said.
One person died on the spot and at least six were injured.
"The condition of three of the injured was stated to be critical," the official said.
The wounded were shifted to hospital with multiple injuries.
"The needle of suspicion is on the NDFB as this is considered a stronghold of the outfit," the official said.
The NDFB is fighting for an independent homeland for the Bodo tribe in Assam.
