Cairo, May 10 (RHC)-- Egypt's riot police have attacked protesters in the capital, Cairo, as well as in the cities of Alexandria and Giza, injuring a number of people and arresting nearly two dozen. Security forces also attacked supporters of ousted president, Mohamed Morsi, at Cairo’s al-Azhar University on Friday.

Eyewitnesses in Alexandria said protesters were attacked when they were holding Friday prayers. Anti-government demonstrators have been holding rallies almost on a daily basis since the army toppled Mohamed Morsi, Egypt’s first democratically-elected president.

The demonstrators say his ouster is a coup and demand that Morsi be reinstated. But Egypt's former army chief and current presidential candidate, Abdel Fattah el-Sisi, said the Muslim Brotherhood movement is finished in Egypt.

Sisi is accused of leading a severe crackdown against the supporters of Morsi and the Muslim Brotherhood. Human rights groups say 1,400 people have been killed in the violence since Morsi’s ouster in July last year, "most of them due to excessive force used by security forces."

Thousands more have been also arrested, including members of the now banned Muslim Brotherhood. Egypt’s Brotherhood has been named a terrorist organization by the military-backed interim government.
