Defence Minister A K Antony has accused Pakistan of "not willing" to act against terrorists infiltrating into Jammu and Kashmir from its side of the border, even after the Mumbai attacks last November.

"The main thing is, even after 26/11, Pakistan is not willing to take strong action against these infiltrators," Antony told reporters here on the sidelines of Defence Accounts Department headquarters building inauguration on Wednesday.

Noting that all these terrorist camps were near to their Army formation, he said if they are sincere they can control it.

"By and large, they are always trying to push maximum number of people into Jammu and Kashmir," he said to a query on reports of a large number of ex-Taliban members waiting to infiltrate from across the border with Pakistan.

Exuding confidence, Antony said Indian armed forces were always ready to prevent infiltration and were maintaining their guard.

"Our armed forces are always taking care...are always on guard. I am sure that our armed forces will be able to prevent it to maximum extent. So, I do not expect a largescale infiltration," he added.

On the role of defence forces in anti-Naxal operations, Antony said, "We don't support armed forces for offensive action against Naxalites. We can give only logistical support and training. But offensive action is not the duty of the armed forces."

Expressing shock over the beheading of a Jharkhand police officer by the Maoists, Antony said that the Naxal problem was a "law and order" problem.

"Mainly it is the duty of the state governments to handle it but Centre can give all-out support to state governments. Already, armed forces are engaged in internal security duties in northeast and Jammu and Kashmir," he added.

Antony said that the government wanted to "minimise" the role of armed forces in internal security duties.

"Using the armed forces for internal security is the last resort," he added.
