Al Jazeera reports: Egyptian President Mohamed Morsi has declared a 30-day state of emergency and a night-time curfew in three cities along the Suez Canal that have seen deadly clashes in recent days.

In a televised address late on Sunday, Morsi said the emergency measures in Port Said, Ismailia and Suez would take effect on Monday from 9:00pm local time (19:00 GMT) to 6:00am (04:00 GMT), warning that more action would be taken to stem the latest eruption of violence across much of the country.

“I have said I am against any emergency measures but I have said that if I must stop bloodshed and protect the people then I will act,” Morsi said.

He also called for dialogue with top politicians starting on Monday to resolve the situation.

Deadly clashes across the country between protesters and police have killed at least 48 people since Friday, when Egyptians commemorated the two-year anniversary of the revolution that toppled former President Hosni Mubarak.
