Images of New Clashes in Egypt, Two Years After the Revolution's 'Day of Rage' Last Updated, 12:34 p.m. As my colleague David Kirkpatrick reports from Egypt, there were protests in the Suez Canal city of Port Said and fresh clashes in Cairo on Monday. Video uploaded to YouTube on Sunday showed officers firing at protesters in Port Said, killing four, including a man in a wheelchair, according to Mosireen, a collective of activist Egyptian filmmakers. As clashes continued in Port Said on Monday, despite a declaration of martial law, journalists and bloggers there uploaded video of angry chants against the government at funerals for protesters and reports of escalating mayhem. In Cairo, police fired tear gas on Sunday and Monday at protesters at the foot of the Kasr el-Nile bridge near Tahrir Square, which was the scene of an epic battle during the uprising against former President Hosni Mubarak exactly two years ago, on what was known as the revolution's "Day of Rage." The activist blogger Omar Kamel shared dramatic photographs and video of the clashes by the bridge on Sunday, showing clouds of tear gas in front of the luxury hotels along the Nile Corniche illuminated by the protesters' fireworks and lasers. The Cairene blogger who writes as Kikhote uploaded video shot from above Tahrir Square on Monday that zoomed in to the foot of the Kasr el-Nil bridge, showing the location of the bridge and what looked like hundreds of protesters gathered there. Kikhote also drew attention to the activist blogger Rasha Azab's photograph of a cloud of tear gas in the air above the heads of protesters near the foot of the bridge on Monday, in front of the distinctive salmon-colored facade of the Cairo Semiramis hotel. Tarek Shalaby, another activist blogger, reported on Twitter that a couple of hundred protesters remained on the bridge, with dozens of officers from the Central Security Forces on the Corniche nearby, at about 2 p.m. on Monday afternoon. A short time later, my colleague Kareem Fahim reported from the bridge that tear gas was being fired at protesters on the Cornche. At abut 5 p.m. local time, Jonathan Rashad, a photographer, reported on Twitter that the officers had pushed protesters back from the Cornche on to the bridge and into Tahrir Square. About two hours later, the Egyptian journalists Mohamed Abdelfattah and Simon Hanna reported from the Corniche that a protest march coming from the other direction had broken through the police lines just down the street from the Semiramis, and, after some fighting, the protesters captured a senior officer outside another luxury hotel, the Kempinski. Witnesses also said that the protesters had taken control of one police armored personnel carrier and set another on fire.
