"India will hit back harder every time it is targeted," he said.
The BJP MP's remarks came after militants in police uniform attacked an Army artillery unit in Nagrota, killing three Army personnel, including an officer, and leaving several others injured.

"It was a statement of policy...Our policy is that we will hit you back every time you hit us. We will hit you back harder. So, I think a couple of more time we hit them back, it will certainly settle in their mind," he said.
