Two U.S. soldiers were killed and another wounded late Tuesday after a bomb detonated near their tank north of Baghdad.

The deaths of the two U.S. soldiers late Tuesday pushed to 117 the number of American soldiers killed in Iraq since President Bush declared major combat operations over on May 1. That is more than the 115 U.S. soldiers who were killed during the war that began March 20.

Two soldiers from the U.S. 4th Infantry Division were killed and another was wounded when a roadside bomb detonated as their vehicle patrol was passing by. The incident occurred about 70 kilometers north of Baghdad.

Also on Tuesday, seven Ukrainian soldiers were wounded south of Baghdad when a roadside bomb exploded as their patrol was passing by. Afterwards the patrol came under attack from gunfire.

There are more than 1,500 Ukrainian soldiers in the Polish-led multi-national force that operates in central and southern Iraq.
