Authorities in Iraq say armed men have kidnapped two German engineers from an oil refinery compound in the town of Baiji, north of Baghdad.
Separately, the U.S. military says two soldiers and two Marines were killed Monday. The soldiers died in a roadside bomb blast in Baghdad, while the Marines were killed in a vehicle accident in western Iraq.
In Baghdad, the trial of ousted Iraqi leader Saddam Hussein and seven co-defendants resumes Tuesday with a new presiding judge.
Monday, the court appointed Raouf Rasheed Abdel-Rahman, a Kurd, to temporarily replace the presiding judge who resigned this month after criticism of his conduct of the trial.
