KARACHI, Pakistan — Gunmen disguised as police guards attacked a terminal at Pakistan's busiest airport Sunday night with machine guns and a rocket launcher, killing at least 11 people as explosions echoed into the night, officials said. A separate suicide bombing in the country's southwest killed 23 Shiite pilgrims returning from Iran, authorities said.
No one immediately claimed responsibility for the attack on the Jinnah International Airport in Karachi, named after the founder of Pakistan, nor the suicide bombing in Baluchistan province. However, the attacks come as government-led peace talks with the local Taliban faction and other militants have floundered in recent weeks.
The airport attack still raged on early Monday in Karachi, a sprawling port city on Pakistan's southern coast, although officials said all the passengers had been evacuated. Heavy gunfire and multiple explosions could be heard coming from the terminal, used for VIP flights and cargo. A major fire rose from the airport, illuminating the night sky in an orange glow as the silhouettes of jets could be seen.
The attack sparked an intense firefight that stretched out for at least five hours. Soldiers joined police officers in fighting the attackers. Military spokesman Gen. Asim Bajwa said in a message on Twitter feed that six gunmen had been killed and three to four were still holed up at the airport.
Senior police officer Ghulam Qadir Thebo told journalists outside the airport that at least 11 people had been killed, not including the attackers. He said the gunmen took shelter in two sections of the airport.
"The blast you heard a little while ago was when our police party went to pick up a body (and) one of the attackers blew himself up," Thebo said
Authorities seized four machine guns and a rocket launcher, Thebo said. He said none of the aircraft were damaged and that the billowing smoke and flames was from oil that had caught fire.
Dr. Seemi Jamali from Jinnah Hospital in Karachi said nine bodies had been brought to the hospital from the fighting. She said seven were Airport Security Force personnel, one was an employee of the Civil Aviation Authority and another was from the state-run Pakistan International Airlines.
Another official who spoke to journalists near the airport said at least some of the gunmen wore Airport Security Force uniforms and all were strapped with explosives. He said one of them tried to capture a vehicle used by the Civil Aviation Authority and when a guard shot at him, the explosives strapped to his body went off. The official said another attacker also blew up after being shot at by security forces.
The official described himself as being with one of the country's intelligence agencies but declined to give his name.
Authorities diverted incoming flights and suspended all flight operations. A spokesman for the Civil Aviation Authority said the airport would be closed until at least Monday night.
Sarmad Hussain, a PIA employee, told The Associated Press he was at the airport at the time of the attack.
"I was working at my office when I heard big blasts — several blasts — and then there were heavy gunshots," Hussain said. He said he and a colleague jumped out of a window to get away, and his colleague broke his leg.
Karachi is Pakistan's largest city and has been the site of frequent militant attacks in the past. It is the country's economic heart and any militant activity targeting the airport likely would strike a heavy blow at foreign investment in the country.
In May 2011, militants waged an 18-hour siege at a naval base in Karachi, killing 10 people in an assault that deeply embarrassed its armed forces.
There was no immediate claim of responsibility for Sunday night's attack. Pakistan's government has been trying to negotiate a peace deal with local Taliban fighters and other militants mostly based in the northwest who have been waging war against the government. But the talks have had little success, raising fears of a backlash of attacks across the country.
Security officials in Karachi had feared that if the talks broke down, their city would be a likely spot for militant groups to strike back as the Pakistani Taliban and their allies increasingly have gained a foothold there.
In the suicide bombing, four bombers targeted Shiite pilgrims staying at a hotel in the town of Tuftan near the Iranian border, said Baluchistan province Home Minister Mir Sarfraz Bugti. One bomber was killed by security officials traveling with the pilgrims, but the other three managed to get inside the hotel where they blew themselves up in an attack that also wounded 10 people, he said.
It wasn't immediately clear whether there was a connection between the airport assault and the Baluchistan attack. But the attacks were sadly familiar for Pakistan, which has seen thousands killed by militants in recent years.
Shahid Ali, who dropped his mother and father off at the airport prior to the attack, said they were onboard a flight when the attack began. Ali said the flight, heading to Iraq, later returned to the terminal without being told what was going on. He said his parents joined other passengers waiting in a lounge.
He said his parents were not panicked.
"We are used to this," Ali told the AP.
