Today, November 19th, marks the first anniversary of Mohamed Mahmoud street deadly clashes that left 42 protesters dead and thousands injured. It was considered one of the deadliest attacks committed by the Egyptian police against protesters. Thousands rallied in the street today to commemorate the first anniversary. There was anger among protesters as one year passed and no one of those responsible for the killings was prosecuted or punished. Protesters clashed with the police near the ministry of interior in downtown Cairo leaving dozens injuries. I arrived at the scene just after the clashes had begun. There were two stories of how the clashes begun, some say it's the protesters who started throwing rocks while others say it's the police who started it. At first, clashes involved rocks throwing from both sides, but an hour later the situation escalated and involved Molotov cocktails. Police fired tear gas canisters and live shots in the air. Dozens were injured due to rocks and Molotov cocktails throwing. There were also cases of suffocation due to the tear gas fired. Motorcycles were used in carrying the injured to the nearest ambulance as the street was crowded and narrow making it difficult for the ambulances to get in. Apart from the clashes, there were flags with pictures of martyrs on them. Graffiti artists drew pictures of martyrs on the walls of the street. Chants were against the ministry of Interior and the Muslim Brotherhood. Protesters called for justice. Different revolutionary groups took part in the event along with families of martyrs. There were symbolic coffins of Mohamed Mahmoud martyrs. I left the scene but it seems that the situation is still escalating and may continue for hours and also may involve other streets in the area.
