Police say gunmen riding on a motorcycle have killed eight Shiite Muslims in a pair of sectarian attacks in southwest Pakistan.

Senior police officer Shaukat Ajmad said assailants opened fire on a car Saturday, killing six people in Quetta, the capital of impoverished southwestern Baluchistan province.

Minutes later, they shot and killed two people in a rickshaw in the same area.

Shiite Muslims are a minority in overwhelmingly Sunni Muslim Pakistan.

Although most Sunni and Shiites live peacefully together, extremists from both sides have targeted each other over the past three decades. In recent years, Sunni attacks on Shiites have been far more common.
