Insurgents in Iraq carried out several attacks in Baghdad Wednesday as a week-long surge of violence in the capital continues.

Officials say three separate suicide car bombings in different parts of Baghdad killed at least two Iraqis and wounded eight others.

The attacks came a day after two U.S soldiers and at least 12 Iraqis were killed in a series of attacks across the country.

A U.S. military spokesman said today the American casualties occurred in a suicide car bomb blast near a U.S. patrol in southern Baghdad.

Al-Qaida in Iraq, the nation's most feared terrorist group, claimed responsibility for one of Tuesday's deadliest attacks, in which six Iraqis were killed and more than 30 others wounded in a car bomb blast at an army recruitment center in Baghdad.

Other attacks killed four Iraqi troops and a Baghdad university professor and his son.
