Bomb blast occured in eastern India on Thursday night in which three killed. A woman & two men were among those killed when a powerful bomb accidentally went off inside a house in West Bengal state’s Siliguri district.

An official of Police said, “The bomb was a powerful improvised explosive device & we are trying to find out what the people inside were up to”.

Police said they were investigating their links with several Madhesi rebel groups operating in the nearby Terai region of Nepal, who are boycotting elections there next week. The Madhesis dominate the Terai, a narrow strip of fertile plains considered to be impoverished Nepal’s food basket and home to nearly half of its 26 million people.

The official said “We are exploring all possible angles & the Madhesi connection could be a real possibility”.
