BBC News reports: At least 29 people have been killed in clashes in Egypt as the country marks the anniversary of the 2011 uprising which overthrew President Hosni Mubarak, the health ministry says.
Rival demonstrations of supporters and opponents of the military-backed government took place in Cairo.
But police broke up anti-government protests, and arrests were reported in Cairo and Alexandria.
Hundreds have died since July when the army deposed President Mohammed Morsi.
Extra security measures were in place for Saturday.
Egyptian Interior Minister Muhammad Ibrahim had urged Egyptians not to be afraid to go to events marking the anniversary of the uprising.
Thousands of supporters of the military and the government gathered in high-profile locations including Tahrir Square – the focal point of the 18-day 2011 popular revolt.
