International rights groups are calling on Saudi Arabia to allow women to drive ahead of a planned day of defiance against a ban on female drivers. Amnesty International wants Saudi authorities to respect women\'s right to drive. The group has expressed astonishment that in the 21st century, Saudi authorities continue to deny women the right to legally drive a car. Human Rights Watch has also thrown its weight behind the Saudi women\'s campaign dubbed \"Women to Drive\". Meanwhile, Saudi authorities have threatened women not to join the campaign on Saturday. Saudi Arabia is the only country in the world which forbids women from getting behind the wheel. Recently, dozens of women have defiantly posted online videos of themselves driving in several Saudi cities. Show Less >>
