A major oil fire raged Saturday after insurgents blew up a pipeline in the north of the country. The family of an anchorwoman for a U.S.-funded state television station - a mother of four who was repeatedly shot in the head - found her body dumped on a street in the northern city of Mosul. Insurgents, meanwhile, killed two civilians in a roadside bombing west of Baghdad, a suicide car bomber killed an Iraqi national guardsman and injured 7 people southwest of the capital and the U.S. military announced the death Saturday of a U.S. Marine during military operations in Babil, just south of Baghdad. Earlier, the military had announced the death of a soldier killed Friday in a massive security sweep in the Sunni Triangle.
