Former Egyptian President Hosni Mubarak waves to his supporters from behind bars as he attends a hearing in his retrial on appeal in Cairo, Egypt, Saturday, April 13, 2013. Egypt's highest court in January ordered a retrial for Mubarak, for failing to stop the killing of 900 protestors in the 2011 unrest that ousted him, after accepting an appeal against his life sentence, citing procedural failings. A high-level inquiry into the deaths of the nearly 900 protesters killed in the uprising, parts of which were released exclusively to The Associated Press last month, could weigh heavily in the retrial.
