Singh said he was was unable to understand why cross- border terror incidents were continuing unabated despite India wanting "good relations" with Pakistan.
"I cannot understand why time and again cross-border terror incidents are taking place when we want good relations with our neighbour (Pakistan). I want to tell our neighbour that we want peace but not at the cost of our national pride,” Singh said.
"I have said this earlier and I will say it again that while we will not be the first to attack or fire, but if challenged, will give a befitting reply (muh tod jawab)," he said here.
Singh is here to take salute from the marching contingents of the Central Reserve Police Force (CRPF) at its cradle here as part of the paramilitary force's 76th Raising Day celebrations.
The country's largest paramilitary was raised in this garrison town in 1939.
Recalling efforts by India for peace between the two countries, he said Prime Minister Narendra Modi invited his Pakistani counterpart Nawaz Sharif to his swearing-in ceremony last year.
Singh said while he was leaving for here the incident was reported from Gurdaspur and action was on as he talked.
"I talked to the Punjab CM, NSA and Home Secretary before leaving for this event. Coming here was important as this day is historic in the life of CRPF and I wanted to meet my jawans and officers here at any cost today," he said.
Singh will make a statement in Parliament tomorrow on the Gurdaspur terror incident. "I will make a statement in Parliament tomorrow on the incident," he said, adding the security forces will get "ultimate success" in the ongoing operation.
