An anti-government protester celebrates after hearing a rumor that Egyptian President Hosni Mubarak will resign near Tahrir Square in Cairo February 4, 2011. Tens of thousands of Egyptians prayed in Cairo's Tahrir (Liberation) Square on Friday for an immediate end to Mubarak's 30-year rule, hoping a million more would join them in what they called the "Day of Departure".
