Roadside bombs in Iraq have killed at least seven people on Saturday.
Officials say five people died in an explosion near the Iraqi Islamic party headquarters in al-Khalis, 60 kilometers north of Baghdad. Another blast in Baghdad killed two policemen.
Meanwhile, Al Jazeera television says five Sudanese who were kidnapped last week in Baghdad have been freed.
Sudan said Friday it was closing its embassy in Baghdad in an effort to win the release of the hostages, who include a diplomat. Al-Qaida in Iraq had threatened to kill the five unless Khartoum severed diplomatic ties with the Iraqi government.
Separately, oil minister Ibrahim Bahr al-Ulum told Voice of America that he does not disagree with a recent government hike in gas prices -- but that it should have been done in stages.
Mr. al-Ulum has been suspended from his post for 30 days, and Iraqi Deputy Prime Minister Ahmed Chalabi is temporarily taking over for him.
