- Preliminary inquiries indicate trap was laid for the BSF team
- Early inquiry also suggests involvement of Lashkar terror group
- Pak has denied violating ceasefire; its army denied any hand in attack
"It could have been a trap," said a top source. "It has to be established conclusively whether the lines were snapped due to Pakistani shelling or it was an act of sabotage," said another source.
While initial reports said the attackers belonged to Pakistan's Border Action Team, sources said early inquiry also suggests the involvement of Lashkar-e-Taiba, the Pakistan-based terror group.
"Information is being gathered on who exactly carried out the dastardly act - Pakistan army regulars or it was a Lashkar unit with tactical support from Pakistan army. But early inquiry suggests Lashkar," an official said.
Pakistan has already denied violating ceasefire and its army has denied having any hand in the attack. Calling India's allegation "false", Pakistan's Inter-Services Public Relation said in a statement, "Pakistan Army is a highly professional force and shall never disrespect a soldier, even Indian".
Union Minister Arun Jaitley has described the killings as "reprehensible and inhuman" and said such acts "do not take place even during war". The army has issued a warning, saying "such despicable act will be appropriately responded".
