Six people were killed on Friday in clashes between Egyptian security forces and backers of the now-outlawed Muslim Brotherhood near Cairo, health and security authorities said.

Supporters of ousted Islamist president Mohamed Morsi had held small marches in Giza after the Friday morning prayers for Eid al-Fitr, which marks the end of the holy Muslim fasting month of Ramadan.

He said four people were also wounded in the clashes.

On August 14 2013 security forces stormed two sit-ins of supporters of ousted president Mohamed Morsi in Rabaa al-Adawiya and in Nahda Square, also in Cairo, resulting in what HRW termed “one of the largest killings of demonstrators in a single day in recent history” of Egypt.

The interior ministry said at least 10 policemen were killed during the dispersal after coming under fire from protesters.

In the city of Alexandria, in the country’s north, security forces used tear gas and water cannon to disperse protesters, sources there told Al Jazeera.

Wagdy denied that a police station in the vicinity had been attacked during the protest.

Senior Health Ministry official Dr. Khaled al-Weshahy confirmed the deaths, saying the bodies of the victims have been transferred to hospitals in Giza.

Ahmed Gamal Ziada, an Egyptian photojournalist who was recently released after 497 days in prison following his arrest while photographing a protest, said that among the dead was 20-year-old Hossam al-Aqbawi, who was reportedly shot in the head.

Scores of Muslim Brotherhood leaders and members, including Morsi, have been sentenced to death.
