Iraqi police say at least five people have been killed and 30 others wounded in clashes between the police and insurgents in western Baghdad Wednesday.
Witnesses say a group of insurgents attacked police checkpoints with at least one car bomb, rocket-propelled grenades, and other weapons.
Iraqi authorities have sealed off the area, a Sunni Arab neighborhood next to Amiriya, a stronghold of Iraq's insurgency.
Earlier, Iraq's deputy justice minister Yosha Ibrahim escaped his second assassination attempt in two days when gunmen fired on his convoy in Baghdad. The attack killed four of his bodyguards.
Meanwhile, Iraq's President Jalal Talabani has urged Sunni, Shi'ite and Kurdish leaders to reach a consensus on a new Iraqi constitution, one day before parliament is scheduled to vote on the charter.
Sunni leaders oppose parts of the document that call for a decentralized government and criticize the former ruling Baath Party. Some Sunnis warn the constitution as it stands will be rejected in the nationwide referendum set for October.
