Muslim Brotherhood (MB) leading figures have urged Gulf Council Countries (GCC) to intervene to thwart death sentences against MB heavyweights including ousted president Mohamed Morsi being carried out, Al-Bawaba News cited MB sources Saturday. MB religious leader Youssef Al-Qaradawy, fugitive in Qatar, the Italy-based billionaire Youssef Nada and other MB International Organization members have held intensified contacts with GCC high-level officials to prevent the rulings being carried out, the sources said. MB claimed a new surge of bombings would torpedo Egypt's security and hence the whole region in case the death sentences were carried out, the sources added. On May 16, an Egyptian court sentenced ousted president Morsi and another 104 codefendants to death over charges of jailbreak and espionage while the convicts had the right to appeal the verdict. "The banned group alleged the Egyptian authorities had paved the way for carrying out the death sentences through executing MBs convicted in a series of terrorist blasts in a case publicly known as ‘Arab Sharkas cell' on May 17," the sources told Al-Bawaba.
