At least 18 people were killed in protests across Egypt marking the fourth anniversary of the 2011 uprising.
Protesters were still in control of the Cairo suburb of Matariya, a Muslim Brotherhood stronghold, yesterday.
Three police cadets were killed in Cairo.
The BBC reported:
At least 18 people have been killed in clashes between police and protesters across Egypt, officials said.
Three police cadets were among the dead, and dozens of protesters were also injured, the officials said.
The clashes follow the death of an activist in a march in the capital Cairo on Saturday.
The protests were staged to mark the fourth anniversary of Egypt’s 2011 uprising, which toppled long-time leader Hosni Mubarak.
Security in major cities was tightened ahead of the anniversary, and key locations in Cairo were blocked off.
Dozens of people were killed in similar protests last year.
The police cadets were killed during protests in Cairo, the officials said, while protesters were also killed in the capital and the northern city of Alexandria.
Leftist protester Shaima El Sabbagh was shot dead in Tahrir Square during the protests.
But police denied using anything but tear gas as they quelled protests.
