A bomb blast has killed at least 32 people and wounded dozens of others outside a Muslim shrine in southwestern Pakistan.
The bomb exploded as thousands of Shi'ite worshippers were gathered for an annual pilgrimage at the shrine to a Muslim saint. The shrine is in the remote town of Fatehpur, south of Quetta, the capital of Baluchistan province. There was no immediate claim of responsibility for the attack but authorities are calling it an act of terrorism.
The Quetta area has a history of sectarian violence between majority Sunnis and minority Shi'ites. Officials do not believe the attack is related to fighting between Pakistani troops and rebel tribesman demanding more autonomy and profits from Baluchistan's natural gas fields.
