Six people were killed and more than 25 people injured in two separate bomb attacks in Iraq today.
A suicide car bomber attacked a convoy carrying Iraq's justice minister this morning, killing four people but leaving the minister unscathed.
Another car bomb in Mahmudiya, just south of Baghdad, killed two Iraqi National Guardsmen and wounded 25 people, the latest in a series of attacks targeting Iraq's security forces.
Insurgents have repeatedly targeted top officials. Earlier this week a regional governor was killed when his convoy was ambushed. In May, a suicide car bomb attack killed Izzedin Salim, the president of the country's Governing Council.
A group linked to Jordanian born al Qaeda ally Abu Musab al-Zarqawi has claimed responsibility for both those attacks.
Zarqawi's group has also beheaded an American and a South Korean hostage, and says it has killed one of two Bulgarians kidnapped in Iraq earlier this month.
Diplomats in Baghdad and Bulgarian officials said a headless corpse in an orange jumpsuit found in the Tigris River on Thursday was probably that of one of the Bulgarians.
Hopes of finding the second Bulgarian alive were fading, they said.
