WASHINGTON (AFP) - US Secretary of State Hillary Clinton on Tuesday publicly threw her support behind a campaign by Saudi women to lift a ban on female driving in the ultra conservative, oil-rich kingdom. "What these women are doing is brave, and what they are seeking is right," Clinton said, ending what officials here had called quiet US diplomacy toward a campaign by Saudi women to defy the ban."I'm moved by it (the campaign) and I support them," the chief US diplomat told reporters after Saudi women had urged her to publicly back their right-to-drive demands.
