CAIRO, Dec 4, (Aswat Masriya) Egypt's government began to rebuild a memorial commemorating protesters who were killed during the January uprising in 2011 in Tahrir Square on Wednesday, an eyewitness said.

Activists have demolished the monument's foundation stone one day before the anniversary of violent confrontations between protesters and security forces where tens were killed, commonly known as Mohamed Mahmoud clashes.

The government erected the base of the memorial last November, which was inaugurated by interim Prime Minister Hazem al-Beblawi.

An Egyptian prosecutor ordered on Tuesday that the founder of the Black Bloc, Sherif al-Serafi, be detained for four days pending investigations for destructing the monument set in Cairo’s Tahrir, center of protests that ousted autocratic Hosni Mubarak in 2011 and Islamist President Mohamed Mursi in 2013.

Police investigations found footage showing the suspect destroying it.
