Egyptian activists protested for a third straight day on Sunday to demand an immediate end to military rule.
At least ten people have died since fresh clashes broke out on Friday.
Demonstrators threw stones at the security forces earlier in protest at the crackdown on the demonstrations.
“The police and military are using excessive force,” said one man. “They say they would protect the revolution.”
The latest protests were sparked when photos circulated online of an injured man who was reportedly beaten by police.
Protesters want the Egyptian military to hand over to a civilian government at once, rather than in June next year.
The army seized power when former president Hosni Mubarak was ousted a popular revolt in February.
