A suicide car bomber has killed at least seven Iraqis at an entrance to Baghdad’s Green Zone, a year to the day since United States forces captured Saddam Hussein.

Nineteen were wounded, four seriously, civilian hospital staff said.

The US military said no US soldiers were hurt in the bombing, which came after seven US Marines were killed in two separate incidents west of Baghdad.

“We had stopped in the car when all we felt was a car explode next to us,” said one injured Iraqi civilian at the city’s busy Yarmuk hospital, his face caked with blood.

A US officer said: “A suicide bomber hit checkpoint 12. It’s pretty ugly.”

Up to thirteen people have been killed in a suicide attack at the entrance to the highly fortified Green Zone in Baghdad, reports say.

The blast occurred when a vehicle that had been waiting in line to enter the zone at its western Harthiyah gate exploded as it drove up to the checkpoint at 9am (1700 AEDT), Iraqi police said.

Fifteen other cars were destroyed in the blast.

Reports on casualties were varied with the Associated Press reporting thirteen people had been killed and 15 injured while Agence France-Presse said six were killed and 19 were injured.
