The Assam Police, following the inputs from National Investigation Agency, foiled a major explosion in the state just days ahead of Prime Minister Narendra Modi's two-day visit later in the week.

The security personnel found at least 7 kg of explosives from near a toilet in a local train, sources said. A Bangladeshi terror outfit is suspected to be behind the incident.

This comes a day after a major explosion took place in northern Assam's Dibrugarh where one person died and as many as 27 people were left injured in the blast.

Prime Minister Modi is scheduled to take part in the All India Directors-General of Police conference in Guwahati.
