Tens of thousands of people have gathered in central Cairo for a seventh day of protest.

As pressure mounts on President Hosni Mubarak to step down, police have been ordered back to the streets to positions they abandoned on Friday.

The President has promised political reform but demonstrators are calling for a general strike and a mass march tomorrow.
