Speaking to reporters here, Antony said, "The army is the last resort in internal security measures and the government does not intend to use it against Maoist activities."
He also said law and order was mainly a state subject, but the Centre was prepared to extend any support, including providing paramilitary forces to deal with any internal security problem.
The role of defence forces was different and the Army would be the last resort in settling problems in states, he said.
Maoists have been operating in states like West Bengal, Orissa, Chhattisgarh and Jharkhand and their ideology of violence would be dealt with firmly, Antony said.
"No one including Maoists, will be allowed to take law into their own hands," Antony said.
