"Log mare to mare unko chinta thi apni kursi ki apne vote bank ki (let the people die, he was more concerned about his chair and vote bank politics)," Modi told an election meeting at the Gandhi Maidan here.
The holy city of Bodh Gaya, he said, was rocked by serial bomb blasts triggered by terrorists in July last year, but the state government did little to prevent it.
With new ally LJP chief Ramvilas Paswan and former Bihar deputy chief minister Sushil Kumar Modi on the dais, Modi claimed that tourists visiting Bodh Gaya had declined because of the terror incident.
He also held the UPA government responsible for the scourge of terrorism "growing" in the country and said it did not have the will to fight it.
The rally witnessed chaos when a large crowd of people broke barricades to enter the media enclosure the moment Modi arrived on the dais.
The situation was brought to control after a mild lathi-charge and appeal from leaders on the stage.
He also criticised the previous state governments in Bihar and questioned why a dam in Latehar in Jharkhand started in 1975 had yet not been completed.
Modi also rubbished the Congress election manifesto and asked the ruling party to first give account of promises made in 2009 before making new promises.
The Congress manifesto promised creating jobs for 10 crore people, he said and asked whether party whose approach was for promoting 'jobless growth' could be believed.
He also berated the promise of creating rural courts in the manifesto, saying out of 5000 promised last time only 152 were set up so far.
Taking potshots at the Congress on the issue of anti- corruption legislation and bringing black money back to the country, he asked, "Can they be believed" he asked.
