Five detainees were wounded in an insurgent rocket attack on Iraq's Abu Ghraib prison Friday.

Military officials said three of the five had serious injuries.

The rocket landed in one of the internment facility's detainee compounds at about 10:15 a.m.

U.S. forces quickly responded to defend the facility and safeguard the detainees, U.S. military officials said. The injured were immediately taken to the 115th Field Hospital.

Officials said no coalition forces were injured in the incident.

Also in Iraq, a 1st Corps Support Command soldier was killed in a vehicle accident after an improvised-explosive-device attack during a logistics patrol north of Taji today. The soldier was evacuated to a nearby medical facility, where he was pronounced dead. The name of the soldier is being withheld pending next-of-kin notification.
