CAIRO: Egypt's government on Wednesday declared a daily curfew in Cairo and 13 other provinces in a bid to contain nationwide violence following a crackdown on supporters of ousted president Mohamed Mursi.

The curfew was to begin at 7:00 pm (1700 GMT), before sunset, and run until 6:00 am (0400 GMT), a government spokesman said in a statement read out on state television.

It applies to the provinces of Cairo, Giza, Alexandria, Beni Sueif, Menya, Assiut, Sohag, Beheira, North Sinai, South Sinai and Suez, the statement said.

The government later added that Ismailiya, Fayoum and Qena would also be under curfew, for a total of 14 out of the country's 27 provinces.

The measure will last one month, the government said, after the presidency announced a month-long state of emergency in the country.

The government said anyone who defies the curfew will face prison.
