CAIRO, Jan 28 (AFP): A state of emergency came into force Monday in three Egyptian provinces hit by deadly rioting, as President Mohamed Morsi scrambled to contain deepening divisions with calls for a national dialogue.

Morsi late Sunday sought to crack down on violence which has swept Egypt since Friday in which more than 45 people have died, declaring a month-long state of emergency in the provinces of Port Said, Suez and Ismailiya.

In a televised address he also slapped the three provinces with night-time curfews, while calling the opposition -- which accuses him of betraying the revolution that brought him to power -- to a national dialogue at the presidential palace at 6:00 pm (1600 GMT) Monday.
