Raipur, March 2 -- Fifteen Maoist cadres of the Balangir-Bargarh-Mahasamund (BBM) division surrendered before the police in Chhattisgarh's Mahasamund district on Saturday night, a police officer said on Sunday. Of the total, one is a Special Zonal Committee Member (SZCM), two are Divisional Committee Members (DVCMs) of the Balangir-Bargarh-Mahasamund (BBM) division, five are Area Committee Members (ACMs), and seven are Platoon Members (PMs), officers said. According to police, the cadres brought three AK-47 rifles, two SLRs, three .303 rifles, three 12-bore guns, two INSAS rifles and one 14 musket (a .303 rifle without a magazine). With the surrender of these 15, the western sub-zone of the Odisha State Committee of Maoists has been completely dismantled, Additional Director General of Police (Anti-Naxal Operations) Vivekanand Sinha said. A police officer said that a local journalist facilitated the initial contact, while state intelligence units played a key coordinating role in the surrender. Police said intensified operations, the establishment of new security camps, improved road connectivity and increased development outreach in interior areas have steadily weakened the Maoist organisation's influence in the district. Two CoBRA battalion personnel were seriously injured in an IED blast triggered by Maoists during an anti-Naxal operation in Jharkhand's West Singhbhum district on Sunday....
