Egypt unrest: 'No middle ground' in Egyptian politics
Fatalities have been reported as Egyptian security forces moved in to clear two protest camps occupied by supporters of deposed president Mohammed Morsi in the capital, Cairo.
The Nahda Square camp near Cairo University has now been completely cleared, according to Egyptian authorities, but protesters remain at the Rabaa al-Adawiya mosque.
The BBC's Middle east Editor Jeremy Bowen said that the unrest was a consequence of "the current violent climate of winner takes all politics in Egypt".
