An alert was sounded at Amritsar Sri Guru Ram Das International Airport, on Tuesday, after reports of the fidayeen attack.
Earlier, it was reported that the Army has taken over the air traffic control of Amritsar airport but later it was known that only Air force had activated its personnel and no army deployment has been made.
According to top sources, intelligence agencies have issued warning against a module of eight to 10 Jaish-e-Mohammed (JeM) terrorists who may try to carry out a suicide attack against air bases in and around areas of Jammu and Kashmir which includes Amritsar and Pathankot airbases as well.
An orange alert has also been sounded for Srinagar, Avantipur, Jammu, Pathankot and Hindan airbases bases after the monitoring of the terrorists' movements by the intelligence agencies. The orange alert is the second-highest level of alert second only to Red alert which, if issued, would entail closing of schools and restriction on movements in airbases.
Senior officers are reviewing security arrangements round-the-clock to tackle the threat, sources said.
