SHARM EL-SHEIKH (Update1) - Egypt's former president Hosni Mubarak suffered a "heart crisis" on Tuesday during questioning over the killing of protesters and embezzling of public funds and is now in intensive care, state media said. Mubarak, ousted on February 11 after 30 years in office, was summoned on Sunday by the public prosecutor as part of the investigation. His sons, Alaa and Gamal, were also summoned by state prosecutors probing accusations of embezzlement. In his first public comments since stepping down and which were broadcast by Al Arabiya on Sunday, Mubarak denied any wrongdoing and described the allegations as "lies." State television said Mubarak, 82, suffered a "heart crisis" during questioning. It said he was taken to a hospital in the Red Sea resort of Sharm el-Sheikh, where he has been in internal exile since leaving office, and was now in intensive care. But a hospital manager said Mubarak was well enough to keep answering questions, Arabiya reported. Justice Minister Mohamed el-Guindy was questioning Mubarak, it said. Arabiya said earlier that Mubarak was being questioned in South Sinai, where Sharm el-Sheikh is located. Mubarak has suffered from health problems in recent years and went to Germany for gall bladder surgery in March 2010. Rumours about his health became more frequent as he aged and were particularly common after his last bout of surgery. Mubarak vowed to die in Egypt when he addressed the country's 80 million people shortly before he stepped down in the wake of mass protests. Al Ahram newspaper reported earlier on Tuesday that Mubarak had received the summons to appear before a Cairo court for questioning and that special security was being arranged. It quoted Interior Minister Mansour el-Essawy as saying Mubarak would give testimony on accusations against him at a court on the eastern outskirts of Cairo. It did not say when he would appear or what the accusations were. Mubarak's family and some political allies have been banned from travelling while state prosecutors investigate the complaints against them. Mubarak said on Al Arabiya that information sent to the prosecutor would show he owned no financial assets or real estate abroad. "I have been, and still am, pained by what I and my family are facing from fraudulent campaigns and unfounded allegations that seek to harm my reputation, my integrity and my military and political record," Mubarak said. He said he had assets and bank accounts in only one Egyptian bank, as he had previously disclosed.
