LAHORE, Pakistan - A group of gunmen, some in police uniforms, attacked a police academy Monday and held it for hours, seizing hostages, throwing grenades and killing at least 11 people before being overpowered by Pakistani commandos.
Six militants were arrested and eight died in the eight-hour battle to retake the compound on the outskirts of Lahore, in eastern Pakistan, said Rao Iftikhar, a top government official in Punjab province.
As the siege ended, black-clad Pakistani commandos fired their guns in the air in celebration at the top of the building, shouting "God is Great!" and "Long live Punjab police!"
Officials said more than 90 officers were wounded and that some of the attackers wore police uniforms.
The highly co-ordinated attack underscored the threat that militancy poses to the U.S.-allied, nuclear-armed country and prompted Pakistan's top civilian security official to say that militant groups were "destabilizing the country."
The attack on the Manawan Police Training School began as dozens of the officers carried out morning drills. About 700 trainees were inside at the time.
"We were attacked with bombs. Thick smoke surrounded us. We all ran in panic in different directions," said Mohammad Asif, a wounded officer taken to a hospital. He described the attackers as bearded and young.
Another officer, Ahsan Younus, told The Associated Press that some of the attackers wore police uniforms and took some of the police hostage.
TV footage showed several frightened police officers jumping over the wall of the academy to flee. Some crouched behind the wall of the compound, their rifles pointed toward the parade ground where police said the attack took place. Farther back, masses of security forces and civilians monitored the tense standoff, taking shelter behind security and rescue vehicles.
The forces had surrounded the compound, exchanging fire in televised scenes reminiscent of the militant siege in the Indian city of Mumbai in November and the attack on Sri Lanka's cricketers earlier this month in Lahore.
Armoured vehicles entered the compound while helicopters hovered overhead. At times, explosions rocked the scene.
At one point, security forces cornered several militants on the top floor of a building on the compound, where the gunmen held about 35 hostages, Iftikhar said.
"The eight hours were like eight centuries," said Mohammad Salman, 23, one of the hostages. "It was like I died several times. I had made up my mind that it was all over."
Police captured one of the suspected gunmen six hours after the initial assault, dragging the scruffy, bearded man to a field outside the academy and kicking him.
Iftikhar confirmed that six militants were arrested. Of the eight dead, two blew themselves up, he said. Army spokesman Maj. Gen. Athar Abbas said eight police were killed, while Punjab police spokesman Athar Khan said three civilians were also among the dead.
On the roof of the building where hostages were kept, an AP photographer saw body parts, blood and spent ammunition strewn about, and several police officers -- apparently hostages -- came out with their hands above their heads in fear.
No militant group immediately claimed responsibility, but Interior Ministry chief Rehman Malik suggested it could have been Lashkar-e-Jhangvi, a Punjab-based al-Qaida-linked terrorist group that has been implicated in several other attacks in the country.
Pakistan has endured scores of suicide bombings and other attacks in recent years, and it faces tremendous U.S. pressure to eradicate al-Qaida and Taliban insurgents on its soil. Most of the violence occurs along the country's northwest border with Afghanistan, but attacks have occurred in all the major cities.
Monday's attack occurred close to the Indian border.
The attacks pose a major test for the weak, year-old civilian administration of Pakistani President Asif Ali Zardari. The U.S. administration has warned Pakistan that militancy threatens the nation's existence, while U.S. officials complain the country's spy agencies still keep ties with some of the insurgent groups.
Malik said Pakistan's integrity was "in danger at this time" and suggested that a foreign country was interfering in the country's domestic affairs, a possible reference to longtime foe India.
"Some rival country, or some hostile (intelligence) agency is definitely out to destabilize our democratic forces," he told reporters in Lahore.
Earlier, he told state-run TV that Pakistan's police were not equipped to fight the wave of terrorism.
"In our country, at our different borders, arms are coming in, Stinger missiles are coming in, rocket launchers are coming in, heavy equipment is coming -- it should be stopped," Malik said. "Whoever the anti-state elements are, they are destabilizing the country."
India's Foreign Secretary Shivshankar Menon told reporters his country was "deeply saddened and shocked by the events in Lahore."
British Foreign Secretary David Miliband released a statement condemning the attack.
The U.S. Embassy in Islamabad issued a warning advising Americans to avoid travel between Lahore and the Indian border and prohibiting its employees from doing the same.
Lahore, a vibrant metropolis considered by many to be Pakistan's cultural capital, has become an increasingly alluring target for militants. The cricket ambush in early March sparked a battle that left six police officers and a driver dead and wounded several players.
Those gunmen escaped unscathed and have not been publicly identified.
Several militant groups operate well beyond Pakistan's northwest. Some of them, including Lashkar-e-Taiba, have their roots in the Kashmir dispute with India, and Pakistani spy agencies are believed to have established them.
Pakistan's stability is of paramount concern to the U.S. which is fighting a growing Taliban insurgency in Afghanistan more than seven years after the American-led invasion ousted the militant regime from power there. Al-Qaida and Taliban fighters are believed to hide out in Pakistan's northwest while planning attacks on U.S. and NATO forces in Afghanistan.
