Bomb Rips Through Pakistan Shrine

An apparent suicide bombing at a shrine crowded with Shiite Muslims celebrating a religious festival near Pakistan's capital killed at least 20 people and wounded dozens of others, witnesses said.

The explosion ripped through hundreds of worshippers as they recited the Quran beneath tents at the Bari Imam shrine on the outskirts of Islamabad — the latest bloody attack on a religious gathering in Pakistan, long troubled by sectarian rivalry.

An AP photographer at the scene counted at least 20 bodies, many of them in pieces, making it hard to give an exact figure. An intelligence official said at least 20 were killed and 150 were wounded.

"It was like hell," said Syed Muktar Hussain Shah, 40, who had been waiting for a prominent Shiite leader, Hamid Moasvi, to address the gathering on the final day of the five-day festival when the bomb went off. "I fell down ... when I woke up I saw dead bodies around me."

"None of the bodies was intact," said Dr. Wahid Abbas, who helped treat the wounded. "Some had legs blown off, some had their hands blown off."

He and other witnesses said police collected the head of a suspected suicide bomber. Authorities did not immediately confirm that information.

Information Minister Sheikh Rashid Ahmed condemned the attackers as "enemies of Pakistan and Islam." He said it appeared to be a suicide attack and at least 14 people had died.

Mukhtar Kazmi, who was running a free clinic at the shrine, said they had treated about 200 people.

The Shiite leader, Moasvi, was not hurt, witnesses said.

The shrine is about one kilometer (half a mile) from the official residence of Pakistani Prime Minister Shaukat Aziz.

Police cordoned off the shrine and blocked access roads after the blast.

Hundreds of Shiite worshippers, weeping and moaning in grief, beat their chests in mourning. Some clashed with police after officers baton-charged the crowd to clear the way for ambulances.

Many of the Shiites also chanted, "Down with America!"

Later Friday, radical Islamic groups planned rallies in Islamabad and other cities in Pakistan to protest the alleged desecration of the Quran by interrogators at the U.S. military prison at Guantanamo Bay, Cuba.

Ali Ahmad, a worshipper who was injured in the blast, said he had seen a man dressed in a police uniform who appeared to be the bomber walk inside as worshippers recited the Quran. Police at the shrine tried to stop the man but failed to prevent the attack, he said.

However, another witness, S.M. Shirazi, gave a different account. He said two bearded men he thought were the bombers entered the gathering and sat near a podium at the front. An explosion then occurred, and the body of one of them flew in the air, he said. He didn't know what happened to the other man.

"Some say it was a suicide bomb, but also, some people are not discounting a remote-controlled bomb going off in the shrine," said Islamabad local journalist Khashif Abbassi.

CBS News Correspondent Larry Miller reports that Abbassi notes that some think it could have also been an al Qaeda attack.

"It is being said that it could also be al Qaeda, but nothing coming from the authorities just yet as an official statement as to why this could have happened," Abbassi said.

Shabbir Hussain, who was sitting away from the gathering, said there was panic after the blast.

"I saw pieces of dead bodies, lots of dust in the air. Then I heard people crying and people wailing and I left because we feared a series of bombs. People were shouting, 'Leave the place, there might be another explosion!"'

Maj. Tubassam Zaheer, a bomb disposal expert, said his team was collecting body parts and clothes of the victims to help determine what type of explosives were used in the attack.

There was no claim of responsibility and the motive was not immediately clear.

There are frequent sectarian attacks in this Islamic country by extremist elements of the Sunni and minority Shiite sects, although most live peacefully together.

The schism between Sunnis and Shiites dates back to a 7th century dispute over who was the true heir to the Prophet Mohammed.

In February, gunmen opened fire on mourners returning from a funeral near the shrine, sparking a firefight that killed three people and injured several others. That violence, however, was believed linked to a feud between two families over control of the shrine.

The last major attack against a religious gathering in Pakistan occurred March 19, when suspected Islamic militants bombed a festival for a Shiite saint at a village shrine in southwestern Baluchistan province, killing at least 46 people.

In October, a suicide bombing at a Shiite mosque killed 31 people in the eastern city of Sialkot. Six days later, a car bombing at a gathering of Sunni radicals in the central city of Multan killed 40 people.
