Roadside bombs hit two US Army convoys southwest of Baghdad on Thursday, killing a total of three soldiers, the military said.
The first attack on an American patrol occurred at about 6:30 a.m., killing one soldier, the US command said.
A similar roadside bomb attack in the same region occurred at about 9 a.m., killing two soldiers, the military said.
No other details were provided, including the exact locations of the attacks, or how many Humvees or other vehicles the bombs destroyed.
The names of the three US Army Multinational Division-Baghdad soldiers were withheld pending notification of their relatives.
The attacks raised to at least 2,428 the number of members of the US military who have died since the beginning of the Iraq war in March 2003, according to an Associated Press count.
