A police official quoted that the base was on high alert following the news that it might be attacked by terrorists on Tuesday night.
“The security clampdown came as the intelligence sounded a warning to the authorities concerned to remain vigilant at the airport," said a police official to the daily Dawn.
According to sources the police informed the authorities in the air base but the security of the base had three big loopholes.
“Yes, the police had intimated the authorities concerned about the loopholes' in the security at the PAF base and on the other sides of the runways and expressed concern over taking the security issue lightly," said the official.
On May 22 militants stormed an airbase in Karachi at late night leaving at least 10 people dead, including six of them, just three-weeks after the death of Osama bin Laden. They also blew up a PC3 Orion aircraft in one of the most brazen attack in years.
