The US military has said a US soldier and two Iraqi civilians were killed in recent violence in Iraq.
The American casualty occurred last night about 40 miles south of Baghdad in the Sunni-dominated "Triangle of Death," a region rife with sectarian violence and the scene of numerous ambushes against US and Iraqi troops.
The bombing raised to at least 2,406 the number of members of the US military who have died since the beginning of the Iraq war in March 2003.
In today's violence, a roadside bomb missed a US convoy in Waziriyah, northern Baghdad, but killed an Iraqi pedestrian. A roadside bomb also missed an Iraqi police patrol, killing one civilian and wounding another in western Baghdad, according to police reports.
Police also found the bodies of four Iraqi men in a Shia neighbourhood in northern Baghdad. The legs and hands of the men were bound with rope, and each had been shot in the head and chest before being dumped on a street, police said.
The US military also announced that Iraq's Central Criminal Court had convicted 12 suspected insurgents in April of crimes such as joining a terrorist group.
They included two men who were given life sentences for joining al-Qaeda in Iraq operations.
