U.S. and Iraqi officials say insurgents killed at least 13 people in several attacks across Iraq Monday.

The officials say two car bombs in western Baghdad killed five people each.  One of the cars exploded near a courthouse.

Insurgents killed at least two people in drive-by shootings outside the capital. 

Elsewhere, the U.S. military in Iraq says a roadside bomb killed an American soldier southeast of Baghdad. 

And the bodies of two Iraqi journalists were found Monday, one day after they were abducted.  Authorities also found the bodies of three police commandos kidnapped last week.

In a separate statement, the U.S. military says troops killed Ali Wali, an explosives expert and member of the Ansar al-Islam terrorist group, during a counterterrorist raid in (the Mansur district of) Baghdad on Saturday.
