Iraqi police say a suicide car bomber attacked a security checkpoint in central Baghdad Monday, killing at least two people and wounding five others, mostly policemen.
The attack took place near a gate into the Iraqi capital's heavily fortified Green Zone, where most U.S. and Iraqi government offices are located.
Separately, the U.S. military said two American airmen were killed and another wounded in a roadside bomb blast on Sunday near an airbase (Taji) north of Baghdad.
In another development, the trial of ousted leader Saddam Hussein is scheduled to resume Tuesday, but it is not yet clear who will preside in court.
News reports say senior officials are urging chief judge Rizgar Muhammad Amin to stay on. The jurist resigned earlier this month after criticism of his handling of the trial. The tribunal has not yet accepted his resignation.
