Suicide car bomber kills U.S. diplomatic security agent and three guards in Iraq

A suicide car bomber attacked a U.S. diplomatic convoy in the Iraqi northern city of Mosul, killing four Americans and wounding two others, a U.S. official said Tuesday.

A U.S. Diplomatic Security agent and three private security guards died when the suicide bomber rammed their SUV, the middle vehicle in convoy of three, said the official on condition of anonymity because he was not authorized to speak on the subject.

He said the victims were attached to the U.S. Consulate in Mosul, Iraq's third largest city, 360 kilometers (225 miles) north of Baghdad.

On Sept. 7, a roadside bomb killed four private American guards who worked as security agents for the Bureau of Diplomatic Security in Basra. The attack was claimed by al-Qaida in Iraq, reports the AP.
