Scott Lucas paints a stark picture:
0155 GMT: Protesters have divided themselves into four groups almost now. The core of the protesters are occupying Tahrir Square like every night. The second and third group - made up of thousands more - are camped outside the parliament and the state TV building and will spend the night there. The fourth group is marching towards the Presidential Palace right now.
2330 GMT: Many sources, including CNN, are speculating that Mubarak did not step down because he may want to lure the protesters into committing acts of violence so he can then crackdown upon them.
