Egypt crisis: 'Deep divide' appearing in country
Egypt's President Mohamed Morsi is trying to appease opposition by annulling a decree which gave him sweeping new powers but this has failed to stop the unrest.
The main opposition coalition has called for mass protests on Tuesday and insists that Mr Morsi withdraws plans for a referendum on the new constitution.
The BBC's Shaimaa Khalil, who is in Cairo, said the country was deeply divided.
