Dawn reports: Three more rocket launchers, five suicide jackets, 15 petrol bombs and five submachine guns recovered from the airport.

Meanwhile, Pakistani Taliban claimed responsibility for the attack, saying it was revenge for the army's air strikes in areas along the Afghan border where the insurgents are based.

We carried out this attack on the Karachi airport and it is a message to the Pakistani government that we are still alive to react over the killings of innocent people in bomb attacks on their villages, TTP spokesman Shahidullah Shahid said.
