An American journalist who spent four months in an Iranian prison was on her way back to the United States Friday. Robert Hugins, public affairs officer at the U.S. Embassy in Austria, said Roxana Saberi left Vienna on a flight bound for Washington, D.C. The 32-year-old journalist had spent a week in Vienna recuperating after being released from prison in Iran. Hugins said she was traveling to Washington with her parents and a family friend. Saberi, who grew up in Fargo, North Dakota, and moved to Iran six years ago, has dual citizenship. She was arrested in late January and convicted of spying for the United States in a closed-door trial that her Iranian-born father said lasted only 15 minutes.
