Eleven car bombs exploded in Baghdad province on Thursday, killing at least 44 people and wounding more than 120 others, Iraqi security and medical officials said.
Two car bombs each hit Sinaa street in central Baghdad, Graiat in its north and Husseiniyah near the city, and one each exploded in Baghdad Jadida and Maamal in the capital's east, and in Dura, Shurta al-Rabea and Bayaa in its south.
Violence in Iraq has reached a level not seen since 2008, when the country was just emerging from a brutal sectarian conflict.
The bloodshed, which has included sectarian attacks, has raised fears of a relapse into the intense Shiite-Sunni bloodshed that cost tens of thousands of lives in 2006-2007.
With the latest attack, more than 390 people have been killed so far this month, and over 5,100 since the start of the year, according to AFP figures based on security and medical sources.
