3 US soldiers killed in bombing south of Baghdad

A roadside bomb killed three American soldiers south of Baghdad as US and Iraqi forces swept through a city to the north where three insurgents had been killed the day before after firing on US troops. The three Americans died in the attack Friday shortly before noon in Babil province, the US military said, giving few other details. However, Iraqi police said the blast targeted a military convoy near Mahaweel, 35 miles (56 kilometers) south of Baghdad. In Samarra, 60 miles (96 kilometers) north of the capital, American and Iraqi forces imposed a daytime curfew and searched neighborhoods looking for insurgents a day after three militants were killed after they opened fire on US soldiers, police said.
