Mehmood said the attack targeted a Shiite Hazara community. Ethnic Hazaras live mostly in Afghanistan, and there are also Hazara enclaves in Afghanistan and Iran.

President Asif Ali Zardari and Prime Minister Raja Pervez Ashraf strongly condemned the bombing and vowed to go after militants.

Earlier this year, a wave of attacks in Quetta left 87 people dead in the Shiite community.
