Egypt security forces use teargas on Friday afternoon to disperse protesters of an anti-Islam film away from the US embassy towards the revolution's square as army builds wall to protect the mission Clashes re-erupted between the protesters near the US embassy in downtown Cairo and police on Friday afternoon. Both sides are throwing stones on each others while the police are lobbing teargas cannisters at the crowd which numbers in the low hundreds. Ahram Online reporters on the scene say that most of the fighting is now taking place in Tahrir Square as security forces try to push demonstrators away from the US embassy premises a few hundred feet away. Earlier on Friday morning the Egyptian army started building a wall around the US embassy to protect it against protesters. Protesters continue their protest for the fourth day before the US embassy voicing their rage over a film produced in the US that mocks Islam and the Prophet Mohamed. More than two hundred protesters have been reported injured in the past 48 hours. The Muslim Brotherhood and varioes Salafists groups have called for peaceful mass protests on Friday outside mosques across Egypt to protest the film.
