On March 7, Saudi Arabia took the extraordinary step of declaring the Muslim Brotherhood a terrorist organization, on par with Hezbollah and al Qaeda. The move came just two days after the kingdom, together with the United Arab Emirates and Bahrain, withdrew its ambassador from Qatar because of Qatar’s alleged support of Brotherhood interference in internal politics.
