CAIRO Egypt's president has declared a 30-day state of emergency and curfew in the three Suez Canal provinces hit hardest by a wave of political violence that has left more than 50 dead in three days.
An angry Mohammed Morsi vowed in a televised address on Sunday he would not hesitate to take more action to stem the latest eruption of violence across much of the country.
The three provinces are Port Said, Ismailiya and Suez.
Morsi June, also invited the nation's political forces to a dialogue starting Monday to resolve the country's latest crisis.
The predominantly secular and liberal opposition has in the past declined Morsi's offers of dialogue, arguing that he must first show a political will to meet some of its demands.
