The US also revealed on Tuesday the deaths of three more soldiers in what it called non-hostile incidents.
Troops from the 3rd Corps Support Command were travelling in a convoy when they were attacked by an improvised explosive device, said Central Command on Tuesday.
The attack took place at approximately 9.30am (05:30 GMT) near the town of Hamariyah, on a highway between the restive Sunni Muslim towns of Falluja and Ramadi, agencies reported. The area is a hotbed of resistance against occupying US-led forces.
The soldiers, whose identities were not disclosed, were taken to the 28th Combat Support Hospital.
The latest death takes the toll of US servicemen officially killed in hostile incidents to 65 since President George Bush declared major combat over in Iraq on 1 May.
But including a surprisingly high number non-combat deaths suffered by US force in Iraq, the combined total has reportedly reached 142 – four more than the 138 US military fatalities before 1 May.

Elsewhere, as many as 3000 US troops swooped on suspected terrorists, bombers and gang members in a massive raid north of Baghdad on Tuesday, the military said.
Troops detained 22 people on suspicion of anti-coalition activities in the morning raids, AFP quoted army spokeswoman Josslyn Aberle as saying.
Among them were seven people specifically wanted for
anti-coalition and terrorist attacks.
"This is an ongoing operation covering parts of our region where
we don't have a significant military presence," said Aberle.
She said the raid was launched to snare "anti-coalition
subversive elements" wanted for a range of incidents, without
