In other developments, hopes have been raised for Sunni Arab participation in Iraq's 15 October constitutional referendum after the Shi'ite-dominated Iraqi parliament reversed
controversial election rules that would have made it harder for Sunnis to reject the document.
Sunni politicians are quoted as reacting positively to the reversal, but some warned they may still urge a boycott of the referendum.
In Washington, U.S. President George W. Bush praised what he called the increasing participation of U.S.-trained Iraqi troops in antiinsurgent military operations.
Bush also welcomed what he called "political progress" in advance of the constitutional referendum.
"On the one hand, we're making progress when it comes to training Iraqis to take the fight to the enemy, we're bringing the enemy to justice, we're on the offense. On the other hand, democracy is moving forward in a part of the world that is so desperate for democracy," Bush said.
White House officials said Bush is expected to respond to criticisms of the situation in Iraq in a speech later today in Washington.
