The U.S. military says three al-Qaida terrorists linked to bombings in Baghdad have been arrested.

It says the three are believed to be associated with al-Qaida's chief bombing coordinator for the Iraqi capital.  The U.S. military says the three surrendered in recent days without a fight after being surrounded by multinational forces.

Meanwhile, Iraqis observed three minutes of silence Wednesday to honor victims of two recent massive suicide bombings.  But the attacks continued, with a suicide bomber killing 10 people in Baghdad.

On the political front, several Sunni members of the committee drafting Iraq's new constitution suspended work following the killing of two colleagues Tuesday.  A U.S. State Department spokesman condemned the killings as the work of terrorists trying to prevent democracy from taking root in Iraq.
