Attack on Karachi airport leaves at least 23 dead

ISLAMABAD - Pakistan Taliban on Monday morning claimed responsibility for the attack at the Jinnah International Airport in Pakistan's southern port city of Karachi.

Militants 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.

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's old terminal used mainly for charter and executive flights.

"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 attack all but destroys prospects for significant peace talks with the government of Sharif, who came to power last year promising to find a negotiated solution to years of violence.

At the airport, gun battles went on for five hours and television pictures showed fire raging as ambulances ferried casualties away. At least three loud explosions were heard as militants wearing suicide vests blew themselves up.

By dawn on Monday, the army said the airport had been secured but heavy smoke rose above the building.

"Ten militants aged between 20 and 25 have been killed by security forces," said a spokesman for the paramilitary Rangers force. "A large cache of arms and ammunition has been recovered from the militants."

Pakistan's paramilitary force said that the attackers were ethnic Uzbeks. Pakistani officials often blame foreign militants holed up in lawless areas on the Afghan border for staging attacks alongside the Pakistani Taliban around the country.

"Three militants blew themselves up and seven were killed by security forces," Rizwan Akhtar, the regional head of the paramilitary Rangers, said in televised remarks. "The militants appear to be Uzbek."

Officials said no aircraft had been damaged.

Earlier, officials said all flights had been diverted.

Peace talks between the government and the Pakistani Taliban have failed in recent months, dampening hopes of reaching a negotiated settlement with the insurgency, which continues attacks against government and security targets.

Pakistan's Taliban are allied with but separate from the Afghan Taliban.
