Authorities say bombings near a revered Shiite Muslim shrine in northern Baghdad have killed eight Iranian pilgrims.

Police say the deadliest strike killed five people among a group of pilgrims resting near the gold-domed Moussa al-Kadhim mosque in the Shiite neighborhood of Kazimiyah.

Nearby, a bus carrying pilgrims was hit by a car bomb in Baghdad's Shiite-dominated Shula area, killing three.

An additional 52 people were wounded in the two attacks. The casualties were confirmed by hospital officials.

Earlier, police said another roadside bomb in central Baghdad killed one passer-by.
