Dramatic video as Thousands Clash With Egypt Riot Police in Cairo

Cairo – At Cairo's Mustafa Mahmoud mosque today, there was at first just the calm rustling of thousands going through the Muslim prayer ritual.

But when the prayer ended, first one voice and then thousands shouted, "The people want the regime to fall!" They poured out into the street, broke through a police cordon, and joined forces with other protesters to present the gravest threat to the regime of President Hosni Mubarak since he took power nearly 30 years ago.

By mid-afternoon, tens of thousands of Egyptians, braving tear gas and water cannons, were converging on Tahrir Square in central Cairo and protests were taking place across the country. Similar scenes were played out in hundreds of mosques in Cairo, Alexandria, and the gritty industrial towns of the Nile Delta.
