Baghdad blasts kill 15

A series of bombings in and around the Iraqi capital killed at least 15 people and wounded dozens on Monday, security and medical officials said.

Four car bombs in Baghdad killed at least 10 people and wounded 39, while two blasts near the capital left at least five more dead and 14 wounded, officials said.

Iraq is struggling to contain a wave of violence that has killed more than 450 people so far this month -- the second month in a row in which more than 400 people have died in unrest.

The violence has decreased from its peak in 2006 and 2007, but attacks remain common, killing at least 200 people each month so far this year.
