Police say the deadliest attack Thursday struck a food tent serving pilgrims on their way to Karbala. They say the blast killed four people and wounded six.
Earlier, officials say a suicide bomber detonated an explosive-laden car at an army post, killing three soldiers and wounding six in the town of Ana, some 330 kilometers (200 miles) northwest of Baghdad.
Police say another bomb blast killed two persons in a town just south of Baghdad.
Hospital officials confirmed the casualty figures. All officials spoke on condition of anonymity because they are not authorized to speak to journalists.
