Four civilians and a CISF jawan were killed when suspected Naxals detonated a bus with an improvised explosive device (IED) in Chhattisgarh's Dantewada district on Thursday, four days ahead of the first phase of elections in the state, police said.
Two personnel of the Central Industrial Security Force (CISF) were also injured in the explosion, the third Naxal attack in 15 days in the poll-bound state.
The attack comes before Prime Minister Narendra Modi's scheduled visit on Friday to Jagdalpur district, about 100 km from Dantewada, to campaign for the BJP.
The IED explosion took place in a hilly area in Bacheli, about 450 km from Raipur, when the CISF personnel were returning to their camp in Akashnagar after purchasing groceries from the market, Dantewada Superintendent of Police Abhishek Pallava told.
The Naxals triggered a powerful IED blast near curve no.6 on the hills, killing a CISF jawan, the bus' driver, conductor, cleaner and another person who is yet to be identified, Pallava said.
The private bus, which was targeted, was allotted to the CISF team deployed in the Bailadila mining area of the National Mining Development Corporation in Dantewada for election duty.
