Security sources entered Al Azhar University on Sunday to stop riots by students belonging to the terrorist Muslim Brotherhood after the demolishing of the wall separating the university from the male dormitory and the launching of firecrackers. The forces stepped in after a call by the university's administration to protect the students' lives and the university property. There has been no information so far on the injury or arrest of any students, sources said. Some students who caused unrest on campus last week were referred to disciplinary councils and banned entry into the university. Female Azhar University students meantime continued their protests on campus
