Iraqi authorities say a bomb explosion aboard a minibus has wounded nine civilians in the Shiite holy city of Karbala.

Saleem Kadhum, spokesman of the Karbala health directorate, says a bomb left in a plastic bag has exploded inside the minibus, injuring nine civilians, including a woman.

Police confirm the injury toll in Friday's attack that occurred some 500 yards from the Shiite shrine to Imam Al-Abbas in the city center. Last week, a nearby mortar explosion killed one person and wounded two others.

Kadhum says some of the injured were passengers and others were bystanders.

Karbala lies 50 miles south of Baghdad.
