Violence in Egypt after emergency law imposedTuesday 29 January 2013 13.05
Egyptian police have fired tear gas at protesters in a fifth day of unrest in which 50 people have been killed.
Emergency rule announced by President Mohammed Mursi covers the cities of Port Said, Ismailia and Suez.
The army has already been deployed in two of those cities and ministers agreed a measure to let soldiers arrest civilians.
Anti-Mursi protesters were out on the streets in Cairo and elsewhere, the second anniversary of one of the bloodiest days in the revolution, which began on 25 January 2011.
Police fired volleys of tear gas at stone-throwing protesters near Tahrir Square.
A 46-year-old bystander was killed by a gunshot earlier, a security source said. It was not clear who fired.
Mr Mursi's opponents accuse him of hijacking the revolution and of listening only to his Islamist allies.
Islamists say their rivals want to overthrow by undemocratic means Egypt's first freely elected leader.
The political unrest has been exacerbated by street violence linked to death penalties imposed on football supporters convicted of involvement in stadium rioting in Port Said a year ago.
