The BJP on Thursday said that by implementing the decision of the judiciary with respect to the 1993 Mumbai serial blasts convict Yakub Memon, the Narendra Modi-led NDA Government has proved its commitment towards a policy of ‘zero tolerance’ against terrorism.Tarun Chugh, the national secretary of the party, said in a statement here that the judiciary and the Government offered every opportunity possible for an accused to defend himself as per law of the country and Memon was hanged only after he had exhausted all the legal options available.
