New Indian Express reports that the Orissa Government has decided to launch a pilot project in the Malkangiri and Rayagada districts to contain the Maoist activity. As per the plan, civic action programme has been taken up in the Maoist-affected areas of the districts by organising public relations and health camps, sports tournaments and tribal festivals. Publicity material highlighting the futility of extremist activities and its negative impact on the development of the region are being produced and these would be distributed in the tribal dominated areas. The modalities and framework of the inter-State joint task force for Orissa-Andhra Pradesh has been worked out and a number of joint anti-Maoist operations have been conducted. Similarly, modalities for inter-State anti-Maoist operations in the Orissa-Jharkhand border have also been worked out. Official sources said that the scheme will be implemented in other Maoist-affected districts in phases.
