A car bomb killed 12 people and wounded at least 20 others in the Iraqi city of Ramadi.
The attack took place near a checkpoint on a busy street in the centre of Ramadi, 100km west of Baghdad. Police were among the killed.
Another bomb in Maeden, southeast of Baghdad, killed one person and wounded seven.
Since the start of 2013 the intensity of attacks on civilians has dramatically increased in Iraq. More than 1,000 people were killed in attacks in July, the worst monthly toll since 2008.
Tensions between Shia, Kurdish and Sunni factions in the power-sharing government have escalated, and the renewed violence has sparked fears of a return to the sectarian bloodshed of 2006-2007.
