My understanding was that Hamas was the Palestinian extgension of the Muslim Brotherhood, which would make them Sunni, if I'm not completely mistaken. (Details on the MB/Hamas relationship.)

Iran is Shia, Hamas is Sunni. Do we need to go over the Sunni/Shia thing again, or are we all still convinced that Saddam and Osama Bin Laden are gay lovers who planned 9/11 together?
