Gurugram: Union Home Minister Amit Shah said on Tuesday that the government headed by Prime Minister Narendra Modi had a "zero-tolerance" policy against terrorism which he called the greatest challenge on the path of development. He also said India has long been a target of Pakistan-sponsored terrorism while speaking here at the 35th Raising Day celebrations of the National Security Guard (NSG). "Terrorism is a threat for humanity and is the biggest developmental barrier. Our country has suffered more than any other country in the world from the plight of terrorism. We are committed to a zero-tolerance policy on terrorism under the leadership of Prime Minister Narendra Modi. Today, because of NSG, I'm confident of our security, "Shah said.
