A series of bomb attacks across Iraq killed at least 12 people and wounded 64 others on Thursday, security and medical officials said.
The deadliest of the attacks took place in Dujail, 60 kilometres (35 miles) north of Baghdad, where two car bombs minutes apart killed seven people. Another five people died in a car bomb in Hilla, south of the capital.
Bombings also took place in Hawija and Karbala.

The attacks come a day after 42 people died in violence across the country, officials said.
No group immediately claimed responsibility for Thursday's violence, but hardline Sunni militants often carry out such assaults in a bid to destabilise the government and push the country back towards the sectarian bloodshed that blighted it from 2005 to 2008.
Attacks in Iraq are down from their peak in 2006-2007, but they are still common across the country.
A wave of violence in Baghdad and north Iraq on Wednesday left 42 people dead and 245 wounded, the bloodiest day in the country since December 17, according to an AFP tally based on reports from security and medical officials.
The violence comes as Iraq grapples with a long-running political dispute, with Prime Minister Nuri al-Maliki facing several protests in hardening opposition against his rule and calls from many of his erstwhile government partners for his ouster.
