He said the Services have been extending full support to the police troops on the ground and the IAF was operating its choppers during night also in Naxal-hit areas.
Asked if the time was right to deploy Army in anti-Naxal operations given the intensity of the attack on Saturday in Chhattisgarh, he said, "There in no proposal like that. We extend our support without direct involvement.The real answer is to strengthen the local police and para-military forces".
The Defence Minister said the Services are providing "full support. In fact day before yesterday, before this tragedy happened, Air Force helicopters were flying at night time. Our support has always been there."
On the Naxal attack, the Minister said, "India is a democracy, there is procedure, there are institutions and there are methods and opportunity for every section to express grievances.But this kind of violence is not acceptable."
