A group of heavily armed gunmen stormed Pakistan's biggest airport on Sunday and at least 26 people were killed in a night-long battle at one of the country's most high-profile targets.
We carried out this attack on the Karachi airport and it is a message to the Pakistan government that we are still alive to react over the killings of innocent people in bomb attacks on their villages," said Shahidullah Shahid, a Taliban spokesman.
The assault on Jinnah International Airport in Karachi, Pakistan's sprawling commercial hub of 18 million people, took place as Prime Minister Nawaz Sharif's government tries to engage Taliban militants in talks to end years of fighting.
The attack began just before midnight when 10 gunmen wearing military uniforms shot their way into the airport.
Gun battles went on for five hours and television pictures showed fire raging as ambulances ferried casualties away. By dawn on Monday, the army said the airport had been secured. But new firing was reported at about 10 am.
No aircraft have been damaged, according to officials.
A reporter for news agency AFP witnessed three huge blasts as suicide bombers detonated their explosives.
Militants, some dressed in army uniform, clashed with the airport's security force who were backed by police, paramilitary squads and elite commandos.
A senior intelligence official said it appeared the militants had aimed to hijack a plane that passengers were boarding at the main terminal, but that when they were repelled they went on the rampage.
"The passenger plane at Jinnah terminal was their target and when they failed to reach there they destroyed two private terminals in frustration," he told news agency AFP.
