Guwahati, December 2:

A bomb exploded in a train coach in India’s insurgency-hit northeast today, killing at least three people and injuring another 29, a state government official said.

The explosion occurred shortly after the train arrived at Diphu railroad station, about 300 km south of Guwahati, the capital of Assam state, said District Magistrate MC Sahu.

The train was heading from Lumding in central Assam to the eastern commercial hub of Tinsukhia, Sahu said.

Today’s blast comes just days after suspected Muslim militants attacked targets across Mumbai, killing at least 172 people and injuring 239.

The blast was not seen as related to the Mumbai attacks.

Two train passengers were killed on the spot and one of the 30 wounded later died in a hospital, said Bhaskar Mahanta, a police official. Two of the wounded were in critical condition.

The bomb was a timed device, left in a bag on an overhead rack of the train coach and it blew off a part of the roof, said another police official, KK Sharma.
