Seven people have been wounded in a car-bomb attack on an Iraqi minister's convoy in Baghdad, Aljazeera said.
Iraq's State Minister for provincial affairs, Saad al-Hardan, escaped an attempt on his life in southern Baghdad on Wednesday.
His convoy came under attack in al-Qadissiya district, south of Baghdad, Iraqi security sources told Aljzeera.
The Sunni Muslim minister was not in the convoy at the time of the attack near the highly fortified Green Zone which houses Iraqi government offices and the US and British embassies.
Medical sources at al-Yarmouk Hospital in Baghdad said seven people, including four of al-Hardan's bodyguards, were seriously wounded.
Last-minute deal
In other developments, Iraqi leaders on Tuesday clinched a last-minute deal they hope will ensure Sunni Muslim Arab backing for the new constitution in a vote just three days away, after a fresh bout of attacks that cost more than 50 lives.
After days of intense negotiations, Shia and Kurdish leaders agreed concessions that would see parliament consider amendments to the charter after new legislative elections are held in December.
The main Sunni Muslim Arab party said it would now be calling for a "yes" vote on Saturday, when 15.5 million registered voters are to cast their ballots on the document that lays out the legal framework for the new Iraq.
"There was an agreement and we are calling for a 'yes' vote," Ayad Sammarai, spokesman for the Iraqi Islamic Party, told AFP. "It will give us the opportunity to review the constitution."
Community fear
Most Sunni Muslims are opposed to the federal provisions of the draft, fearing it could lead to the break-up of the country.
The constitution will be adopted if a majority of voters approve the text and if two-thirds of voters in three or more provinces do not reject it.
Jawad Maliki, the number two in Prime Minister Ibrahim al-Jaafari's mainly Shia party Dawa, said a committee to be set up after the December vote would have four months to consider possible amendments to the charter which will then be put to another referendum.
