At least 17 people were killed and at least 36 wounded in three car bombings in the Iraqi capital Baghdad on Wednesday, police said, dpa reported.
The blasts occurred in residential area sin the north and east of the city.
Attacks, mostly blamed on Sunni militants, are almost daily occurrences in Iraq.
Last month, militants of the Islamic State in Iraq and the Levant (ISIL) took control of the city of Fallujah, as well as vast areas in Ramadi, the capital of the Sunni-dominated western province of Anbar.
Sectarian tensions erupted in Anbar after troops loyal to the Shiite-led government had cleared out a Sunni protest camp in Ramadi, a key city of the province.
The violence in Anbar has raised the prospect of a return to the sectarian bloodshed that pushed Iraq to the brink of civil war in 2006 and 2007.
According to UN estimates, 8,868 people were killed in 2013, Iraq's highest annual death toll in five years.
