The unprecedented voter turnout in Lok Sabha polls in insurgency-hit south Chhattisgarh has apparently upset the Naxals, who are holding meetings to express disappointment over participation of tribals in the electoral process, according to Intelligence inputs.

Some key leaders of outlawed CPI (Maoist) in Dandakaranya region recently held meetings in areas where they found huge participation of people in polling in spite of their poll boycott call and asked villagers about it, IB sources said.

"In some pockets of Bastar, Dantewada, Kondagaon and Narayanpur, Naxal leaders reportedly held meetings with villagers recently after the Lok Sabha election in Bastar constituency," a senior state IB official said.
