KARACHI: Gunmen from the Tehreek-e-Taleban Pakistan (TTP) attacked a security post outside Pakistan’s Karachi airport on Tuesday, a day after an all-night siege by the militants left 37 dead and shredded a tentative peace process.

The attack on the security post targeted an entry point to an Airport Security Force (ASF) camp 500 meters from the airport’s main premises, and around a kilometer from the passenger terminal.

Police, paramilitary rangers and army all raced to the site but officials reported there had been no casualties and they had not traded fire with the militants.

“Two people came toward the ASF checkpost and started firing,” Col. Tahir Ali, a spokesman for the force told reporters. “Nobody has been killed or injured,” he added.

Army spokesman Maj. Gen. 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.

Flights resumed after temporarily being suspended for the second time in as many days, Abid Qaimkhani, a spokesman for the Civil Aviation Authority, told AFP.

The TTP later claimed responsibility for the attack, saying they were in response to air strikes in the tribal areas.

“Today’s attack on ASF in Karachi is in response to the bombardment on innocent people in Tirah Valley and other tribal areas. We will continue such attacks,” spokesman Shahidullah Shahid said, referring to Pakistani air strikes of suspected militant hideouts.

Meanwhile, Pakistani jets launched air strikes on a militant-infested tribal district in apparent retaliation for Monday’s siege.

The military said nine “terrorist hideouts” were destroyed in the raids, launched after the TTP stormed the Karachi airport.

The strikes were the latest in a succession of attacks carried out by the Pakistani military in the tribal belt this year after talks with the TTP broke down.

The last was in North Waziristan in late May, killing at least 75 people and triggering an exodus of some 58,000 people — half of them in the past few days in fear of a ground offensive that has been anticipated for years.

Also on Tuesday, Pakistani authorities recovered the burned remains of seven Karachi airport workers who hid in a cold-storage facility during a TTP attack, as one tearful relative recounted his nephew’s final phone call.

Shahid Khan said his 32-year-old nephew Inayat’s last words were to his wife, whom he called at 11:25 p.m. on Sunday night as the raid by militants armed with guns, grenades and rocket launchers began.
