Days after a court convicted 49 people for the Ahmedabad serial blasts, Prime Minister Narendra Modi on Sunday said he had vowed to punish the perpetrators even if they took refuge in "paatal", and accused the Samajwadi Party of being sympathetic to such terrorists. Addressing a BJP campaign rally in Hardoi in Uttar Pradesh, PM Modi slammed the Samajwadi Party for being sympathetic towards terrorists and claimed that the previous government headed by it had sought to withdraw cases against several terror accused. PM Modi said, "When I was the chief minister of Gujarat, the Ahmedabad serial bomb blasts took place. I can never forget that day when the earth was reddened by the blood of the victims of the serial blasts. There were uncontrolled tears. I picked up the blood-soaked soil and took a 'sankalp' (vow) that my government will track these terrorists, even from 'paataal' (netherworld), and punish them."
