Polba: Railway Minister Mamata Banerjee on Saturday night alleged the joint security operation against Maoists in Jangalmahal area of West Bengal was in effect only helping the ruling CPI(M) and demanded raids should also be conducted elsewhere in West Bengal to unearth arms stockpiled by the Marxists.

"I see no difference between Maoists and Marxists who are also unleashing terror in different parts of the state including vast areas of Hooghly and elsewhere," the Trinamool Congress supremo told a party workers' meeting here.

While the joint forces are launching operations in forested areas of West Midnapore, Bankura and Purulia districts, armed CPI(M) cadre have turned on Trinamool Congress activists in Arambagh, Goghat, Tarakeswar, Chandrakona Town and many other ares but no raids were taking place to seize their weapons, Banerjee said.

However, the Trinamool would not resort to violence to counter CPI(M) as it believed in the "power of ballots and not in bullets", the TC supremo said.
