In Washington, U.S. President George W. Bush praised Iraqis for turning out in large numbers to vote in the referendum.
"My first reaction to the vote was that an increase in turnout was an indication that the Iraqi people are strongly in favor of settling disputes in a peaceful way," Bush said.
The U.S. military, meanwhile, says it killed 70 suspected insurgents near Al-Ramadi on 16 October. Eyewitnesses, however, said at least 39 civilians were among those killed by U.S. bombs and rockets. The U.S. military said its air raids were in reaction to an attack earlier by insurgents.
