Meanwhile, three Sunni Arab members of the committee drafting the country’s new constitution were gunned down as they left a Baghdad restaurant on Tuesday. The Sunnis on the committee were seen as central figures in the U.S.-organized constitutional process. Fifteen Sunni members joined it last month, making it the first nationwide political body to include significant Sunni representation since the new government took power in April. Resistance groups have sworn to kill any Sunnis that took part. As we went to air, there were reports that the Sunni members were pulling out of the committee.
