Promising to usher in development and transformation in Odisha's Malkangiri district, Odisha Chief Minister Naveen Patnaik on Tuesday said smartphones will be provided free of cost to all households in the region. He also called upon Left-wing extremists (LWE) to shun violence, return to the mainstream and become part of developmental activities in the region. "The 'cut-off area' of Malkangiri always remains in my heart, and I will try my best to make it one of the developed areas in the state," Patnaik said.
