Hundreds of people supporting a US journalist imprisoned in Iran have gathered for a vigil on a bridge connecting two cities in Minnesota, radio station KFGO-AM reports. North Dakota Gov. John Hoeven said the rally Saturday at the Veterans Memorial Bridge recognizes Roxana Saberi's plight and asks that she and her family "be allowed to return home." Saberi's father says the Fargo native went on a hunger strike after she was convicted of espionage in Iran and sentenced to prison last month. The trial was not made public and lasted one day. Her parents are in Iran trying to persuade the government to release her. Concordia College president Pamela Jolicoeur says Saberi is an "inspiration." Saberi had been scheduled to speak at her alma mater's commencement this weekend.
