At least two were killed and 30 injured when a bomb exploded in the passenger coach of a train in India's northeastern state of Assam at about 7:50 in the morning, officials said on Tuesday.

The passenger train runs between Guwahati and Tinsukhia in Upper Assam. The blast took place at around 7:50 am on Tuesday, local NDTV reported.

Prior to blast, another serial blasts occurred in Assam on October 30, which killed many people.

An ethnic insurgent group has been fighting for wide autonomy in the state for the past five years.

Last week a serial terror attacks hit Mumbai, the finance center of India, killing at least 162 people and injuring over 240.
