Egypt's ruling military council imposed an overnight curfew in the area around the defence ministry in Cairo after one soldier was reported killed and hundreds wounded in clashes there.
Soldiers used water cannons and tear gas against protesters on Friday.
Dozens of people were arrested. Protesters later dispersed and some joined a protest in Tahrir Square.
On Wednesday, unidentified assailants attacked protesters outside the ministry, leaving at least 20 dead.
The protesters, who were demonstrating against the ruling Supreme Council of the Armed Forces (Scaf), accused the government of orchestrating the attack.
The curfew was in force from 23:00 to 07:00 (21:00 to 05:00 GMT) Read More
