US forces have carried out multiple bombing raids in the flashpoint Iraqi city of Fallujah, killing five people.
A doctor at a hospital in the city said six people were also wounded in the bombings.
Fighting resumes in Najaf
Fighting has resumed in the Iraqi holy city of Najaf after peace talks broke down between the Iraqi government and rebel Shi'ite Muslim militia.
The country's interior ministry has ordered Iraqi and multinational forces not to attack Najaf's holiest Shi'ite shrine, where hundreds of followers of radical cleric Moqtada al-Sadr are believed to be holed up.
Iraqi police have urged local and foreign journalists in Najaf to leave the city as they would not be able to guarantee their safety.
A conference on the creation of an interim assembly for Iraq is continuing in Baghdad despite the fresh violence. Religious and political leaders are due to elect a 100-member interim council ahead of free elections next year.
The conference is a tentative step towards democracy, but has been overshadowed by a large explosion near the venue. The blast came two hours after three mortar bombs exploded beside the convention centre.
The mortar bombs fell on a bus station near the venue a few hours after the conference opened, killing two people and injuring at least 17.
The conference should help pave the way towards the first post-war elections in January.
Representatives of the Shia cleric Moqtada Sadr are absent from the conference.
