"There can be no business as usual after the barbaric act," the prime minister said when journalists asked about the government's move to hold back visa on arrival for senior Pakistani citizens.
He was speaking at a get-together here hosted by army chief General Bikram Singh on the occasion of Army Day. The visa on arrival was to start Tuesday.
"Those responsible for the heinous act will be brought to book," Manmohan Singh said.
The prime minister was referring to the Jan 8 killing of two Indian soldiers in Jammu and Kashmir, about 600 metres away from the Line of Control (LoC).
One of the soldiers was beheaded and his head taken away by the raiders. The other soldier's body was mutilated, Indian officials say.
The brutality has outraged India.
