A suicide car bomber killed two U.S. soldiers and wounded 25 others on Thursday, the U.S. military said.
The attack brought to five the number of Americans who have died in Iraq since Wednesday.
The suicide bomber struck just after noon west of Baghdad.
It said the wounded soldiers were evacuated by helicopter to a military hospital. Of the 25 wounded, six have been returned to duty and 15 were listed as not serious.
Also in Baghdad, one soldier died from wounds early Thursday after his unit came under attack by small arms fire. Another soldier died after his vehicle was struck by a roadside bomb south of Baghdad.
A soldier attached to the 25th Combat Aviation Brigade of the 25th Infantry Division died from wounds received Wednesday by enemy fire near Mosul.
At least 2,676 members of the U.S. military have died since the beginning of the Iraq war in March 2003, according to an Associated Press count.
Violence has flared in Baghdad despite a monthlong security operation by thousands of U.S. and Iraqi troops aimed mostly at stopping the killings carried out by Sunni and Shiite death squads.
