A suicide bomber on a motorbike rammed into a minibus carrying security personnel, detonating a blast Monday that killed at least six people and wounded more than 30, officials said - the latest in a series of attacks in the Pakistani garrison city of Rawalpindi.

The bus was destroyed and several other people were wounded in the explosion on a road running through a bazaar near the offices of the army's National Logistics Cell, said Bisharat Abbasi, the local police chief.

The bus was carrying doctors and security personnel, said a security official who spoke on condition of anonymity because he was not authorized to speak to the media. The blast, which occurred around 7:30 a.m., blew the roof off the bus and damaged several nearby vehicles.

Shaukat Khan, owner of a nearby tire-repair shop, said he was sweeping the sidewalk at the time. "It was very powerful," he said, adding that the bomb sent splinters that struck a wall beside him. Police and troops arrived at scene of the attack a few minutes later and transported the dead and injured to hospitals, he said.

In recent months there have been a series of suicide bombings in Rawalpindi, a city where the army has its headquarters, about seven miles from the capital, Islamabad. President Pervez Musharraf was in his office several miles from the scene at the time of the blast.

On Dec. 27, opposition leader Benazir Bhutto and about 20 others died in a gun and bomb attack in Rawalpindi.

Prior to that, attacks hit security forces and employees of Pakistan's Inter-Services Intelligence agency, including two suicide bombings against a bus of ISI employees and an army checkpoint on Nov. 24 that killed up to 35 people.

There have been no claims of responsibility for the attacks, but authorities have blamed Taliban militants based near the Afghan border who pose a growing security threat across Pakistan.

The latest attack came just a week after a U.S. missile strike killed a top al-Qaida commander, Abu Laith al-Libi, in a remote tribal village near the border with Afghanistan.

Pakistan and Washington have yet to confirm the death of al-Libi. It was first reported Thursday on Islamic extremist Web sites and confirmed by an American official who said the veteran al-Qaida leader was hit by a missile from a U.S. Predator drone in a village in North Waziristan.

Although it has not confirmed the killing, Pakistan has since stepped up security, apparently to avoid possible retaliatory attacks by militants.
