Pakistan's Information Minister says authorities are trying to determine a motive for a bomb blast at a Shi'ite shrine in Baluchistan province that killed at least 32 people late Saturday. Sheikh Rashid Ahmed says the administration is considering whether it was a suicide attack, a planted bomb, or the result of a sectarian or personal dispute. Local authorities say the bomb exploded as devotees were eating supper at the shrine in Fatehpur village, some 350 kilometers south of Quetta. The shrine holds the tomb of Syed Raqil Shah, a Shi'ite Muslim saint who died in the 19th century. The event was attended by both Shi'ite and Sunni Muslims, as well as minority Hindus. At least 16 people were wounded in the blast, some seriously.
