At least 12 protesters and a policeman were killed in unrest in Egypt on Sunday as the country marked the fourth anniversary of its 2011 uprising, officials said.

Eleven pro-Muslim Brotherhood protesters were killed in clashes in the north Cairo neighborhoods of Matareya, Ain Shams and Haram, and another in the Mediterranean city of Alexandria, a health ministry official told Agence France Presse.

The interior ministry said protesters shot dead a police conscript in the north Cairo clashes.

In central Cairo, police fired shotguns and tear gas to disperse hundreds of protesters who tried to march on Tahrir Square, the epicenter of the early 2011 revolt that ousted veteran autocrat Hosni Mubarak.

Egypt witnesses daily protests since President Abdul Fattah Al-Sisi toppled Brotherhood President Mohammad Mursi in June 2013.
