Baghdad: Iraqi officials say a bomb left inside a minibus has killed two commuters and wounded nine others in Baghdad.

A police officer says the bomb exploded when the bus reached the northern Shiite neighbourhood of Kazimiyah around 10:30 a.m. on Monday.

Two revered Shiite Imams are buried in Kazimiyah and Shiite pilgrims converge from  inside and outside Iraq to the site.

The area's big market also attracts thousands of shoppers every day.

A health official at a nearby hospital confirmed the causality figures.

Both officials spoke on condition of anonymity as they are not authorized to release the information.

Violence has ebbed in Iraq in recent years but militants still launch deadly attacks around the country.
