The Pakistani Taliban has now claimed responsibility for the second deadly attack on Karachi Airport in Academy, less than 28 hours since the Monday deadly attacks.
Officials say gunmen on motorbikes shot at a security training camp just outside the airport and fled.
Subsequent firing which lasted for up to an hour was shots fired by the army and police at the scene, officials say.
Flights at the airport are resuming. The Pakistani Taliban say they carried out both attacks.
Tuesday\’s gunfire came within 48 hours of an assault on Karachi\’s international airport that killed at least 36 people and wounded dozens more.
"It was not such a big attack. Two people came towards the ASF checkpost and started firing," Colonel Tahir Ali, an army spokesman, said on Tuesday.
"They ran away after the firing and because we are on high alert. Under the standard operating procedure we called in [paramilitary] rangers and the army."
Fighters from the Tehreek-e-Taliban (TTP), or Pakistani Taliban, disguised as police guards stormed a terminal of Karachi airport in the early hours of Monday, setting off explosions.
The TTP later claimed responsibility for the assault and gave warning of more attacks.
