Malkangiri, Nov 11: To the last resort, the Maoists have made a last effort to regain their lost ground. The men and women on Wednesday participated in a huge congregation in a village in Vishakhapatnam close to Odisha border. The participants owing allegiance to Rayat Kuli Sangha, a frontal organization of the CPI (Maoist), took out a massive rally and condemned the joint operation of Andhra-Odisha police in the cut-off region of Malkangiri where 30 rebels were gunned down on October 24. In view of this, state police have intensified combing operations here.
