Protesters seeking to force Egypt's president from office are gearing up for a second day of action, after hundreds of thousands thronged the streets of Cairo and cities around the country and marched on the presidential palace.

Some spent the night in dozens of tents pitched at the capital's central Tahrir Square and the palace, positions organizers say they will hold until Mohammed Morsi resigns. Protesters are calling widespread labor strikes to start Monday, although unions have yet to give a read out regarding how much they plan to participate.

Aside from renewed presence at Tahrir and the palace, organizers are also calling for a sit-in at the Cabinet building, interim parliament, and another presidential site where Morsi was staying during Sunday's rally.
