Update at 6:15 a.m. ET. Like Woodstock?

From Tahrir Square, Al Jazeera’s Dan Nolan tweets that:

“Protestor handing biscuits out to all in the heart of the square. It feels kinda like an Egyptian version of Woodstock at the mo!”

— 5:25 a.m. ET: It’s midday in Cairo and the BBC writes that correspondent “Lyse Doucet in Tahrir Square says the crowds there are already much bigger than on previous days.”

According to Al Jazeera, more than 100,000 demonstrators are already there. it also reports that the Army continues to provide security, without taking any actions to hinder the protests. Al Jazeera is again streaming its coverage online.

NPR’s Lourdes Garcia-Navarro, who is in the square, says some of the demonstrators may march to the Presidential Palace later. Al Jazeera, though, is reporting that the march to the palace may be delayed until Friday.

Meanwhile, “the mood is extremely ebullient this morning,” Lourdes reports, in part because last night the nation’s new vice president — Omar Suleiman, who — said he has been instructed by Mubarak to to negotiate with all political parties on Constitutional and legislative reform. Protesters, Lourdes says, think that’s a sign that Mubarak’s days in power are numbered. Copyright 2011 National Public Radio. To see more, visit http://www.npr.org/.
