"The NSA will brief Leader of the Opposition in Lok Sabha Sushma Swaraj and her counterpart in the Rajya Sabha Arun Jaitley Tuesday," government sources told IANS.
Army chief Gen Bikram Singh Monday said his forces "reserve the right to retaliate" after a strong protest was lodged with the Pakistan Army at the flag meeting along the LoC, which divides Jammu and Kashmir between the two countries.
Pakistan denied the charge, news reports said.
The Jan 8 killing of Lance Naik Sudhakar Singh and Lance Naik Hemraj - who was decapitated - in the Mendhar sector in Poonch district of Jammu and Kashmir by Pakistani troops was a "gruesome and an unpardonable act", said the Indian army chief.
Bharatiya Janata Party president Nitin Gadkari, Sushma Swaraj and party leader Rajnath Singh met the family of Lance Naik Hemraj earlier in his home town Mathura in Uttar Pradesh.
Gadkari demanded that the Indian government should "isolate" Pakistan.
"The Pakistani government is provoking people with what they are doing," he told reporters, demanding an apology. "The government should isolate Pakistan as the incident has disturbed not just the family of the slain martyrs but also every Indian," he added.
