EARLIER: Peter Greste marks 300 days behind bars An Egyptian court handed down jail terms in June ranging between seven and 10 years for the three journalists. US President Barack Obama has led international calls for their release. Greste, Egyptian-Canadian Mohamed Fadel Fahmy and Egyptian Mohamed Baher were accused of supporting the black-listed Muslim Brotherhood, and spreading false information. "When required by the state's supreme interests, the President may extradite (foreign) defendants, whether convicted or standing trial, to their countries to either be tried or serve their sentences, upon the request of the public prosecutor," read the decree issued by Sisi on Wednesday. An accompanying statement by his office added that the measure was taken to "preserve Egypt's international image." An Egyptian court is scheduled to hear on January 1 an appeal by the three journalists against their conviction. Although Sisi has previously stressed that he does not interfere in Egyptian court rulings, he mentioned more than once that he wished the journalists had been deported rather than prosecuted.
