CAIRO (AFP) - Egypt's ousted president Hosni Mubarak, whose trial on charges of ordering the killing of anti-regime protesters is due to start in August, has stomach cancer, his lawyer Farid al-Dib said on Monday. "He has a stomach cancer and the tumours are growing," the lawyer told AFP. The former president is currently in custody at a hospital in the Red Sea resort of Sharm el-Sheikh where he has been since suffering heart problems during questioning on April 13. Mubarak, who turned 83 in May, and his sons Alaa and Gamal are set to face trial on August 3 on charges of ordering the killing of protesters during the uprising in January and February that toppled the veteran leader.
