0650 GMT: The Million-Person March has begun. Al Jazeera is interviewing participants who are walking from Abu Zaabal. The correspondent near Tahrir Square speaks of a "cross-section" of protesters, including women and children, and an enthusiastic atmosphere. The military, which has pledged not to use force against the march, has deployed a line of tanks from Tahrir Square to the Presidential Palace. This includes strongpoints in front of the State TV building, which the march will pass, and at the Palace.
Army presence still quite low around Tahrir square. No police (traffic, riot, otherwise) to be seen in the vicinity. Cell phones remain up in Cairo. As far as I know, internet remains down.
