Amnesty International protested outside the Saudi Arabian embassy in London on Thursday to call for the release from prison of women who campaigned for the right to drive.<br /><br />Protesters drove past the embassy beeping their horns and held placards with slogans in support of the women. <br /><br />In June, Saudi women were allowed to drive for the first time, however, according to Amnesty International, some of the women who successfully campaigned for that right are now locked up in a Saudi prison, including Loujain al-Hathloul, Iman al-Nafjan and Aziza al-Yousef.<br /><br />"These women were instrumental in lifting the (driving) ban - yet the Crown Prince Mohammad Bin Salman is now claiming credit for it as one of his ‘visionary reformist policies,'" said Amnesty International in a statement. <br /><br />Amnesty is asking members of the public to write to the Saudi Arabian embassy in London to call for the immediate release of these women.
