Police in Iraq say bombs targeting Iraqi security forces have killed at least seven people in Baghdad.

Officials say two bombs exploded nearly simultaneously Monday as a police patrol passed by in the New Baghdad district in the east of the capital.  The blasts killed three civilians and wounded 10 others.

Another roadside bomb struck an Iraqi military truck that was carrying ammunition in the Yarmouk district.  Three soldiers inside the truck were killed and four civilians were wounded.

A fourth bomb went off today in Baghdad's central Karrada district, killing at least one civilian and wounding several others.

Insurgents have frequently targeted Iraqi security forces in a bid to disrupt recent security gains that have led to a sharp, overall decline in violence.

The U.S. military has been transferring security responsibilities to the Iraqi government as part of a new deal that calls for U.S. forces to withdraw from the country by 2011.
