Three U.S. citizens who disappeared last week in Baghdad were kidnapped and are being held by an Iranian-backed Shi'ite militia, two Iraqi intelligence and two U.S. government sources said on Tuesday. The U.S. sources said Washington had no reason to believe Tehran was involved in the kidnapping and does not believe the trio are being held in Iran, which borders Iraq. "They were abducted because they are Americans, not for personal or financial reasons," one of the Iraqi intelligence sources in Baghdad said.
