Some items recovered from the possession of slain terrorists clearly point the finger at Pakistan for cross-border terrorism. The Indian government has reportedly given evidence of terror group Jaish-e-Mohammad's involvement in the attack on Indian Air Force Base in Pathankot. Defence Minister Manohar Parrikar along with the chiefs of Air Force and Army will visit Pathankot today. The hijacking of Police Superintendent Salwinder Singh's car by terrorists disguised in uniform should have set off alarm bells and helped prevent the deadly weekend attack on the Pathankot air base. However, a second senior officer in the Punjab Police told Reuters, on condition of anonymity, that Singh's call to a colleague in the early hours of Friday morning was not taken seriously "because his record has not been clean". The police sources said Singh had just been transferred after a woman constable filed a sexual harassment case against him. Reacting strongly to the Pathankot air base terror attack, Shiv Sena on Tuesday took on Centre saying that the Narendra Modi government must avenge death of our soldiers. The Indian Air Force is likely to constitute a Court of Enquiry to probe alleged lapses at the Pathankot air base, which was attacked by Pakistan-backed terrorists on Saturday. The terrorists infiltrated the base on Saturday, leading to fierce gun battle with security forces. Four terrorists were killed on Saturday after 15 hours of fighting. The fifth terrorist, according to the security forces, was killed on Monday. Firing could be heard from inside during Monday night and early Tuesday. Officials said the firing was linked to the mopping operation. The US expects Pakistan will take actions against the perpetrators of the terror attack on IAF base in Pathankot, a top American official said, hours after Islamabad said it is working on the "leads" provided by India. "The government of Pakistan has spoken very powerfully to this and it's certainly our expectation that they'll treat this exactly the way they've said they would," State Department Spokesman John Kirby said yesterday. Pakistan has said it is working on the "leads" provided by India on this attack. Search and combing operation by security forces continued on Monday night also. The operation was stepped up on Tuesday to scan every inch of the air base, an Air Force official at the base told IANS. The counter offensive against the terrorists at Punjab`s Pathankot air base has been going on for the past 77 hours. Security forces continued search and combing operation inside the Pathankot air base on Tuesday -- the fourth day after the attack on the frontline Air Force Station (AFS) by suspected Pakistani terrorists.
