The U.S. military says warplanes bombed a suspected rebel safehouse in the city of Fallujah Thursday, killing two people.
A statement says the target was a "meeting site" used by allies of wanted terrorist Abu Musab al-Zarqawi.
Residents say two brothers were killed in the airstrike. Relatives of the victims denied the men were insurgents.
Meanwhile, in Baghdad an American soldier and at least one Iraqi civilian were killed today by a car bomb explosion in the southern part of the city.
On Wednesday, an Iraqi Foreign Ministry official was shot and killed in the capital. Authorities say they believe the official was killed in a botched kidnapping attempt.
Elsewhere, more than 800 British troops have been moving from southern Iraq to a violent area near Baghdad, to free U.S. troops for an expected offensive against insurgents in Fallujah.
