IIRC, the Salafist are battling for control against the MB, we might want to wait and find out more about who these protesters are.
how can the salafist be battling with the Moslem Brotherhood? the salafist are he same as the Waahbi - fundamentalist Muslims whom want to go back to the glory days of Islam.
the conflict mainly is the uneducated the masses (shitite) do not like to ruled by the educated elite (Waahbi, Salafists) Sunni. The problem in the Middle East Arabi Countries is the elite - academics are the ones whom are in control and want the world on fire. The battle in the Mideast is that Shittite want theri 12th Imam and the Sunni do not believe in the 12th Imam.
Arab countries will fight for power - who is behind the uprising in Egypt - Iran. Just like Iran is behind Syria, Hamas and Turkey. Shittite Muslims are the trouble.
