The US military says an American soldier has been killed by a roadside bomb in Baghdad. The military says the attack occurred during a combat patrol by the Multi-National Division - Baghdad soldier in eastern Baghdad. A brief statement gives few details, but eastern Baghdad is a predominantly Shiite area that has seen heavy fighting in recent days by militiamen angry over a government crackdown. Thursday's death raises the number of American service members who have died since the war started five years ago to at least 4,004. That's according to an Associated Press count.
