“It was not such a big attack, two people came towards the ASF (Airport Security Force) checkpost and started firing,” Colonel Tahir Ali, a spokesman for the force told reporters on Tuesday. “Nobody has been killed or injured,” he added.

Army spokesman Major General Asim Bajwa confirmed the incident was over, but said three to four assailants were involved.

“3-4 terrorists fired near ASF camp, ran away. No breach of fence, no entry. Chase is on, situation under control,” he tweeted.

The attack occurred at around 12.30pm local time at a checkpost guarding the entry to an ASF camp 500 metres from the airport’s main premises, and around a kilometre from the passenger terminal.

Ali said the attackers “ran away after shooting and because we are on high alert, under the standard operating procedure we called in (paramilitary) rangers and the army”.

He added that ASF personnel had fired in the air but had not exchanged gunfire with the militants.

A security checkpost outside Pakistan’s Karachi airport has been attacked by gunmen, an official spokesman told AFP, a day after an all-night siege by the Taliban left 37 dead.

TV footage showed paramilitary vehicles and ambulances racing to the scene of the attack.

“We have suspended all flight operations at Karachi airport and we are evacuating passengers,” said Mashud Tajwar, a spokesman for Pakistan International Airlines.

The checkpost is located at the entrance of an ASF camp some 500 metres away from the main airport premises.

The assault came as Pakistan launched air strikes on a militant-infested tribal district, killing 15 people in apparent retaliation for the Monday assault.
