Key Al Qaeda Bomb Maker Believed Slain

U.S. Sources Think Terrorist Killed In Pakistani Airstrike

(CBS/AP)  "Efforts are under way to investigate further," said Shah Zaman Khan, director-general of media relations for Pakistan's tribal areas bordering Afghanistan.

He said authorities were also looking for two prominent pro-Taliban clerics accused of harboring militants, Maulana Faqir Mohammed and Liaqat Ali, who were allegedly in Damadola and survived the assault.

Intelligence officials say the dead foreigners could be aides of Ayman al-Zawahri, bin Laden's top deputy, who is thought to have sent them in his place to an Islamic holiday dinner to which he'd been invited in Damadola on the night of the attack.

Hours after the attack, an Associated Press reporter visited the village, which consists of a half-dozen widely scattered houses on a hillside about four miles from the Afghan border.

Residents said then that all the dead were local people and no one had taken any bodies away. However, it appeared feasible bodies or wounded could have been spirited away in the darkness after the attack, which took place about 3 a.m.

Islamic custom dictates that bodies be buried as soon as possible, and the reporter saw 13 freshly filled graves with simple headstones and five empty graves alongside them — apparently prepared for more dead. When the reporter returned the next day, the five empty graves were filled in, apparently because no more bodies had been found in the rubble.

The only tidbits of official information that have surfaced since then have come from provincial authorities, and they have yet to give a list of the dead. But Pakistani intelligence officials have said they believe some of those killed were Pakistani militants and that their bodies were also removed from the scene.

A Pakistani army official has told the AP that some bodies were taken away for DNA tests — information at odds with reports from provincial authorities. The federal government has not confirmed the report about DNA tests.

Pakistan maintains it was not given advance word of the airstrike, which was reportedly carried out by unmanned Predator drones flying from Afghanistan.

Thousands have taken to the streets in protest over the attack, denouncing the U.S. and Pakistani President Gen. Pervez Musharraf, who ended Pakistan's support of the Taliban regime in late 2001 and has himself been targeted by al Qaeda attacks.

Nevertheless, allegations persist that Pakistan harbors dangerous Islamic militants.

On Wednesday, more than 5,000 people marched through the Afghan border town of Spinboldak, chanting "Death to Pakistan" and "Death to al Qaeda" to protest a suicide attack at a fair this week that killed 21 people.

Afghan officials claim the bomber — the latest in about 25 suicide attackers to strike in Afghanistan in the past four months — trained in Pakistan. Islamabad denies giving sanctuary to terrorists.
