In demonstrations across the country on Sunday, protesters were killed in Cairo, the El-Matariya district just north of Cairo, Damanhur, Alexandria and in Giza. A security conscript was also killed in the El-Matariya district protest.

Egyptian authorities tightened security in Cairo and other cities in anticipation of the protests. Police sealed off several main squares in Cairo, including Tahrir, and beefed up security at vital state installations.
