Guwahati: A grenade exploded at a market place in Bordumsa in upper Assam's Tinsukia district on Thursday afternoon. Police say no one was injured in the grenade blast.
The blast comes just a day after the banned United Liberation Front of Asom (ULFA) protesting against the proposed visit of Prime Minister Dr Manmohan Singh called for an "Assam Bandh" on April 20.
"The ULFA has called for a day long bandh to protest against the Prime Minister's visit on April 20", an e-mail sent by the outfit to the local media said on Tuesday.
The Prime Minister is scheduled to inaugurate the platinum jubilee celebration of the state assembly on that day.
Earlier, the event was scheduled to be held on April 7, which is the outfit's "raising day" but subsequently the Prime Minister's visit was cancelled.
"The ULFA will oppose the visit as many cadres have been eliminated by the Indian security forces in the past", the mail said.
