Deaths, Injuries as Factions Battle in Cairo

The constitutional crisis has turned violent

Three people have died and 350 have been injured in clashes in the Egyptian capital, Cairo, as unrest grows over a controversial draft constitution.

Rocks and petrol bombs were thrown as supporters of President Mohammed Morsi tried to break up an opposition sit-in outside the presidential palace.

Opposition leaders have accused the Muslim Brotherhood of organising the violence.

The government says a referendum on the constitution will go ahead this month.
