An Iranian-American journalist jailed by Tehran for espionage has appealed against her eight-year sentence, the judiciary said Tuesday. Judiciary spokesman Alireza Jamshidi said he hoped the verdict against U.S.-born Roxana Saberi would be changed, the official IRNA news agency reported, without elaborating. Her father Reza said he could not confirm the appeal had been lodged but that he saw “positive steps toward justice” in the case and hoped she would be freed by a higher court
