Tens of thousands of people have gathered in central Cairo for a seventh day of protest, calling for a general strike.
Police have been ordered back to the streets, to positions they abandoned on Friday, but it is not clear whether they are returning to central Cairo.
The demonstrators are also planning a huge march to take place on Tuesday.
Protesters want President Hosni Mubarak to step down after 30 years in power. He has promised political reform.
