Clashes in Mohamed Mahmoud street continue. By: Basil El-Dabh Clashes erupted between police forces and protestors leaving people injured as thousands filled Mohamed Mahmoud Street and hundreds more the nearby Tahrir Square. Official injury count from the Ministry of Health affiliated Mounira Hospital treating serious injuries is 20 while Tahrir Doctors said it was 42. A field hospital doctor told Daily News Egypt at least 300 people were injured. Most injuries were sustained due to exchange of rocks between protesters and police as well as suffocation from the tear gas canisters police fired at protestors, both the field hospital doctor and an EMT at an ambulance confirmed. “There were [also] some injuries due to buckshot”, said the field hospital doctor. The clashes erupted in the middle of demonstrations held to commemorate the Mohamed Mahmoud battle and the 90 people who died a year ago. Chants calling for the fall of the regime and the Ministry of Interior filled the street while men selling gas masks toured offering protestors to “protect themselves from the tear gas." Motorcycles were frequently seen carrying the injured from the front-lines, where a wall was built earlier today to separate police and protestors, to field hospitals or ambulances. The clashes consisted mostly of rock throwing on both sides although police fired the occasional tear gas canister and less frequently, buckshot. Earlier in the evening there were reports of rubber bullets being used. Ultras groups also made their way back to the street, bringing with them fireworks and drums, chanting for their martyrs from last year's clashes and the Port Said massacre last February. Protestors were angry that victims of last year's clashes are yet to be avenged; only one police officer is standing trials over the clashes. President Mohamed Morsy has since made major General Ahmed Gamal El-Din, chief of general security and in direct command of the police during the clashes last year, Minister of Interior. Morsy and the Muslim Brotherhood did not escape protestor's chagrin either. A huge side on the entrance to Mohamed Mahmoud from Tahrir Square bearing the words “no entry for the Muslim Brotherhood" was hung. The Brotherhood decried protestors this time last year, accusing them of attempting to derail parliamentary elections and the democratic transition.
