CAIRO: A Security source said that Gamal and Alaa Mubarak, the sons of Egypt's former President Hosni Mubarak, have not left cell number two in Tora Prison, where they have been held since April 13. The source also falsified reports on them driving a car on a bridge in Cairo. The source also said that the prosecutor carried out investigations with them in side prison regarding their involvement in cases of corruption. Determining a place for their trial has not yet been finalized because of the difficulties regarding the security situation. The trial for Mubarak's sons is scheduled to take place on August 3.
