In a statement today, chief prosecutor Hisham Barakat said the decision follows a February court ruling that convicted Brotherhood leader Mohammed Badie; his deputy Khairat el-Shater; the head of the group's political party and others of orchestrating violence in 2013 that killed 11 people and wounded over 90 outside their office.
The clashes were at the start of mass protests against President Mohammed Morsi, also a member of the group, and days before the military ousted him.
