Security forces in northwestern Pakistan have killed a group of militants in Peshawar, a day after a Taliban raid on the city's airport.

Authorities say security forces stormed a building Sunday near the airport where five militants had taken refuge after the attack on the airport Saturday.

Officials say three militants were killed in a shootout with security forces Sunday, while the other two militants detonated their suicide vests.

Earlier, authorities said Saturday's militant attack on the airport left at least four civilians and five militants dead. Dozens of other people were wounded when the insurgents attacked Peshawar's international airport with rockets and explosives from a suicide bomber.

The Taliban has claimed responsibility for the airport attack.
