India’s Federal Law Minister Ravi Shankar Prasad said there was a deep sense of outrage about the attack in the border town of Uri.
He though added, “Whatever decisions the government takes in this regard will be done with full diplomatic and strategic maturity.”
Prasad also warned against loose talk of conducting cross-border strikes.
Two days after 18 Indian soldiers were killed, in the biggest blow to security forces in the disputed Himalayan region for years, some officials called for a measured response and plotted a diplomatic offensive to mount pressure on Pakistan.
Pakistan has dismissed Indian allegations of involvement in the Uri attack, saying the administration of Prime Minister Narendra Modi had apportioned blame even before the investigation was complete.
On Tuesday, a team from India’s National Investigative Agency gathered evidence from Uri including blood samples, DNA and the GPS devices that the four attackers carried. The assailants were killed by the army.
Indian government officials are claiming they can establish the route they believe the gunmen took to cross the LOC allegedly from the Pakistani side.
An official at the Indian interior ministry said the government was preparing to make a case before the United States to encourage it to take economic measures against Pakistan.
Washington has already cut back military and economic aid to Pakistan, in part because it says Islamabad did not target the Pakistan-based Haqqani militant network blamed for a widening insurgency in Afghanistan.
