Egypt unrest: Morsi declares emergency in three cities

Egyptian President Mohammed Morsi has declared a state of emergency in the cities of Port Said, Suez and Ismalia after days of deadly unrest.

A daily curfew from 21:00 to 06:00 will be imposed for 30 days from Monday, he said in a speech to the nation.

At least 33 people died over the weekend in Port Said, where a court judgment sparked rioting.

In Cairo, anti-government protesters clashed with security forces near Tahrir Square for a fourth consecutive day.

The BBC's Aleem Maqbool, in Cairo, says the "tough speech" was in response to days of violence.
