Two people have been killed and more than 600 injured in fierce clashes between protesters and security forces in Cairo and Alexandria.
The clashes came as police moved to prevent a long-term sit-in following a huge demonstration in Cairo against the military leadership on Friday.
Some protesters lobbed rocks and a police vehicle was set on fire.
The latest violence comes just over a week before parliamentary elections are scheduled to begin.
Protesters – mostly Islamists and young activists – have been holding demonstrations against a draft constitution that they say would allow the military to retain too much power after a new civilian government is elected.
