Two Taliban gunmen riding motorcycles have launched a second attack at Karachi airport.
The men approached the airport’s security academy and opened fire.
Airport security retaliated and the gunmen fled.
Authorities say the attackers emerged from a slum close to the airport’s perimeter.
There are no casualties and flights in and out of Karachi have resumed.
The latest violence follows Sunday’s raid in which 36 people, including ten Taliban gunmen were killed.
The Taliban have claimed responsibility for both attacks.
Sunday’s carnage was in response to the death of the groups leader, Hakimullah Mehsud, killed by a US drone strike in November.
The Pakistan military is on high alert and earlier launched an air offensive on Taliban positions close to the border with Afghanistan.
