(CBS News) CAIRO, Egypt - The president of Egypt has declared a state of emergency in three cities. Anti-government demonstrations are raging in the cities of Port Said, Suez and Ismalia.
Riot police are also battling back against protesters in central Cairo exactly two years after protests there led to the overthrow of Hosni Mubarak.
The rallying cry now is that after only 200 days in office, President Mohammed Morsi must go.
Opponents accuse Morsi and his Muslim Brotherhood party of not delivering economic reforms and not living up to pledges to represent all Egyptians.
"None of the goals of the revolution we made two years ago have been achieved," said protester Maher Hamam. "There is no bread, no freedom, no dignity."
President Morsi went on state TV to announce a 30-day state of emergency and an overnight curfew in three Egyptian cities.
In one of them -- Port Said -- riots and protests at a mass funeral for dozens killed on Saturday brought at least four more dead, dozens wounded, and more than 400 suffered from teargas inhalation, according to a hospital spokesmen.
Hundreds of masked rioters stormed and set fire to a police station in the coastal city of Suez Saturday after clashes which left eight dead, including a policeman.
Military patrols have taken to the streets to restore order, and the local commander said the army had requested authority to arrest lawbreakers.
The Egyptian president called for dialogue, but more demonstrations are planned for Monday.
