The holy month of Muharram is of special significance to Shi'ite Muslims, who are a prime target of al Qaeda's Iraqi affiliate and other Sunni Islamist insurgents seeking to re-ignite the kind of sectarian violence that gripped the country in 2006-2007.
The deadliest explosion took place in the disputed and ethnically-mixed city of
Kirkuk, 250 km (155 miles) north of the capital , where four bombs
planted in parked cars went off simultaneously, killing nine people and
wounding 30, police said. Baghdad
