We are going to deal with this sternly."He said the central government "will adopt a zero tolerance policy" towards terrorism and declared that "there would be no talks at any cost" with such militant outfits.The comments from Rajnath Singh, who flew into Assam Wednesday evening, came as the death toll in the Tuesday horror in Kokrajhar, Sonitpur and Chirang districts rose to 73 Thursday, officials said.Those slaughtered include 21 women and 18 children. Scores of others have been injured in the mayhem. On Wednesday, three more tribals died when police fired at thousands who took to the streets. Rajnath Singh said 50 companies of paramilitary forces had been rushed to the state, and the army and Assam Rifles had been asked to cooperate with the police to control the situation.The minister asked the Assam government to take time-bound action and promised all help from the central government.
