A pair of Taliban suicide bombers have reportedly struck one of Pakistan's most important Sufi Muslim shrines, killing 42 people and injuring 100 who were celebrating the anniversary of its founder's death with music, meditation and other practices abhorred by Islamist militant groups.
Another bomber was wounded when his explosive vest partially detonated. He was arrested along with a fourth militant who was seized before attacking, police official Ahmad Mubarak said.
The attack on the Sakhi Sarwar shrine ended a months-long respite in a relentless militant campaign against the shrines founded by ancient adherents of Sufism, a mystical branch of Islam that sees dancing, chanting and visiting holy sites as expressions of devotion to God.
Taliban spokesman Ahsanullah Ahsan called AP to claim responsibility for the assault.
"It was a huge blast. People were running in panic," said Fida Bakhsh, 42, a vendor outside the shrine.

A stampede followed the bombings, but it was not immediately clear if that caused any casualties.
Local and foreign Islamist militants have carried out hundreds of attacks in Pakistan over the last three years, targeting government buildings and security forces, Western targets like embassies and hotels as well as religious minorities and Muslim sects they consider heretical.
An assault on the shrine of Hazrat Ali Hajveri, known as Data Sahib, killed 47 people in the city of Lahore in July. The attacks have angered many Pakistani Muslims, who see visiting saints' shrines as the best way to communicate to God.
The government and the army have tried to crack down on the militants, but have struggled to unite the nation against the threat and face persistent allegations they are protecting some extremists.
Many Islamist politicians do not publicly criticise the militants, preferring to spread conspiracy theories that American or Indian agents are responsible. These views are widely aired, often uncritically, in some media.
