In Egypt, thousands of protesters are gathering at demonstrations in Cairo, Alexandria, and many other cities, calling for an end to the 30-year rule of president Hosni Mubarak:

The rallies had been promoted online by groups saying they speak for young Egyptians frustrated by the kind of poverty and oppression which triggered the overthrow of Tunisia’s president. Egyptian blogger Hossam El Hamalawy said technology was important in facilitating “the domino effect” needed for demonstrations like this one to progress.

Amazing video here, a “Tienanmen Square” moment in which (around 1:21) a man (soon joined by other) faces off an approaching tank water cannon vehicle. And another here, just two of many eyewitness shots of the mass gatherings unfolding today. Lots more here.
