SHARM EL-SHEIKH (Update 7)- Former Egyptian President Hosni Mubarak's health has deteriorated and he will be flown to a military hospital in Cairo, Egyptian sources told Gulf News. "Mubarak is still in the Sharm el-Sheikh hospital after suffering a heart attack during questioning and will be moved to one of the military hospitals in Cairo," a source told Gulf News. The ailing president was hospitalized in Sharm el-Sheikh after suffering what officials described as a "mild heart attack" Tuesday while undergoing questioning on corruption charges. Earlier Wednesday, the state prosecutor said the president and sons Gamal and Alaa would be remanded for 15 days in police custody, Israel Radio said. The sons were flown by helicopter to the Tora Prison in Cairo early Wednesday where they will undergo questioning on charges of corruption and abuse of power, Ahram Online reported. An unnamed source told the Egyptian Web site, Gamal and Alaa arrived at the prison at 6 a.m. wearing track suits and were unshaven. "Gamal did not look like the Gamal we have seen on TV. He is in a state of total disbelief," the source told Ahram Online. Former aides and officials who served under Mubarak are currently being held at the Cairo jail, including former Prime Minister Ahmed Nazif and former Minister of Interior Habib el-Adly, charged with ordering the killing of the anti-government protesters earlier this year, Ahram Online said. Business tycoon Ahmed Ezz and Zakariya Azmi, Mubarak's former bureau head and Sawfat el-Sherif the former secretary general of the ruling party are also incarcerated there, the Web site said. Earlier, Egyptian Justice Minister Abdel Aziz el-Guindy said Mubarak's condition had stabilized and questioning would resume where he is being held under heavy guard in the hospital's VIP wing on the fourth floor, Ahram Online said. Since Mubarak's arrival at the hospital, the facility was closed to the public except in cases of emergency and a heavy security presence deployed to prevent anti-government protesters from entering, Israel Radio said.
