A suicide car bomber has killed seven Iraqis and wounded 11 others close to an entrance to Baghdad's fortified Green Zone, where several Western embassies are located.
The central area, known officially as the International Zone, houses diplomatic missions, including the US embassy.
The blast was near Baghdad's July 14th suspension bridge, which leads into the zone.
Baghdad police said that two of those killed were soldiers.
A police spokesman said that the vehicle exploded as cars were waiting at a checkpoint.
