Baghdad car bombings kill dozens

A wave of car bombs in Baghdad has killed 32 people and wounded dozens, the latest attacks in a months-long surge in violence.

Attacks have been on the rise in Iraq since a deadly security crackdown in April on a Sunni protest camp. More than 3,000 people have been killed in violence during the past few months, raising fears Iraq could see a new round of widespread sectarian bloodshed similar to that which brought the country to the edge of civil war in 2006 and 2007.
