Car bombs exploded in four Shiite-majority areas of Baghdad today, killing at least six people, security and medical officials said.
The bombs in Kadhimiyah and Sadr City in north Baghdad and Mashtal and Baghdad Jadida in the capital's east also wounded at least 29 people, the officials said.
Violence in Iraq has fallen from its peak in 2006 and 2007, but attacks remain common, killing more than 200 people in each of the first four months of this year.
