KARACHI (Reuters) - A Pakistani Navy commando was the first to detect Taliban militants attacking a naval aviation base in the city of Karachi on Sunday night. He was dead within seconds.
The small group of militants, as few as six, who attacked the PNS Mehran naval aviation base in Karachi gave its defenders no time.
"You cannot imagine how quick they were," said a Pakistani security official who asked not to be named. "When they entered, one of the Navy commandos saw them and tried to react."
He never got the chance.
"It was a single shot in the darkness which took his arm off," the official said. "You can imagine how good they were." The commando died on the spot.
It was about 10.30 p.m. when he died, and the violence didn't end until 16 hours later on Monday afternoon.
The al Qaeda-inspired militants bent on avenging Osama bin Laden's death at the hands of U.S. special forces on May 2 killed 10 Pakistani troops and wounded 20.
It took about 100 commandos, rangers and marines to kill four militants and recapture the base, further humiliating the military. Two militants are believed to have escaped.
In just three weeks, the military has been accused of incompetence in failing to stop the U.S. raid that killed bin Laden and complicity in hiding him.
The attack calls into question the military's ability to secure the country's borders and nuclear weapons.
How did the militants get into one the country's most heavily guarded bases and hold off commandos and soldiers for so long?
Some security officials said it must have been an inside job because of the obstacles to entering. The attackers probably travelled along a dirt lane running beside cinder block shacks at the rear of the base.
In order to get in, they had to cross a long, thick sewage path, elude guards in towers, set up a ladder, scale a 12-foot wall, and cut through barbed wire.
The security official said the assailants were dressed in black with night-vision goggles and armed with Russian hand grenades, rocket launchers, assault rifles and suicide vests.
They fired rocket-propelled grenades at aircraft and fuel tanks, sending huge flames into the sky.
Within a short time, a rapid reaction force from the base tried to engage the raiders, but they retreated to a main building at the sprawling base where they would hole up for the rest of the siege.
Who were these militants?
The security official said the militants looked foreign, with fair complexions, perhaps Chechens or Uzbeks. Foreign militants tied to al Qaeda's international network are known to train in Pakistan's unruly tribal areas along the Afghan border. Many of them are allied with the Pakistani Taliban.
PROTECTING THEIR ASSETS
By 2.30 a.m. on Monday, the initial fighting had ebbed. As jet fuel burned around them, both militants and the military were looking for a plan.
Commanders didn't want to launch a full-scale assault because they feared further damaging aircraft and infrastructure. Fires had already claimed hangars and damaged other aircraft.
"If we had tried to kill them quickly they might have blown themselves up near our assets and caused more damage. We did finally manage to push them away from our assets," said an intelligence official.
The militants' plan was direct: Kill, and be killed.
Pakistan officials say the main operation to retake the base was over by 9.30 a.m., followed by a search and clear operation lasting until the afternoon. There was scattered gunfire and occasional explosions throughout the day.
"Clearly there was a (security) breach," said another security official. "In my personal view there had to be some help from the inside - to brief the militants about the area, and location."
"Our forces should have done better. But at the end of the day, if there are suicide bombers who have already decided to die, I don't think you can stop them," said Shabbir Hussain, a car dealer who lives behind the base.
The civilian government has called a defense committee meeting for Wednesday, two days after the assault, showing a surprising lack of urgency. The military has remained silent. But Pakistanis are more anxious than ever.
"Our military ... has the best and most sophisticated weapons to counter its 'enemies'," wrote the English-language Daily Times. "But the terrorists have the will and patience to fight them out."
