Roadside bombs killed eight American soldiers in separate attacks in Diyala province and Baghdad, and a car bomb claimed 30 more lives in a wholesale food market in a part of the Iraqi capital where sectarian tensions are on the rise. In all, at least 95 Iraqis were killed or found dead nationwide Sunday, police reported. They included 12 policemen in Samarra, among them the city's police chief, who died when Sunni insurgents launched a suicide car bombing and other attacks on police headquarters. The deadliest attack against US forces occurred in Diyala, where six US soldiers and a European journalist were killed when a massive bomb destroyed their vehicle, the US military said. Two US soldiers were wounded, the military said. Two other American soldiers died Sunday in separate bombings in Baghdad.
