Today marks the second anniversary of the start of the Egyptian Revolution, but two years later, the fight looks like it's only just beginning. Protestors in Cairo filled the now-familiar Tahrir Square on Friday, not just to mark the date, but to vent their anger at the regime that replaced the one they fought so hard to bring down.

Protesters chanting slogans and bearing signs that criticize President Mohammed Morsi charged the presidential palace, where they were met by barbed wire, riot police, and tear gas. They also mobbed Tahrir, where hours earlier, police had torched the demonstrators' tents in an attempt to drive them from the area. Chants of "Bread, freedom, social justice" mirrored those used in the original uprising in 2011.

The clashes continued into the afternoon on Friday, with protesters hurling rocks and small fire bombs at armed police, who responded tear gas and fire of their own. At least 100 people have reportedly been wounded in Cairo. Protests have also broke out in Alexandria, Ismailia, and other Egyptian cities where offices of the ruling Muslim Brotherhood party have been burned. The party chose not to hold any competing rallies to mark the anniversary. 

In another repeat of the uprising of 2011, some incredibly powerful images have come out of today's protest. We've gathered some photos, video, and reactions below.
