(CNN) – American hiker Sarah Shourd is free, but her fiancé, Shane Bauer, and friend, Josh Fattal, are still being held in an Iranian prison. The three Americans were detained after they allegedly strayed across an unmarked border into Iran while hiking in Iraq's Kurdistan region in July 2009. Iran accused the three of spying, a charge the United States and the hikers have denied. An Iranian prosecutor said Wednesday a trial will commence soon. Journalist Roxana Saberi spent 100 days in the same, notorious prison before she was finally released last year. She joined us on Thursday’s American Morning to help us understand what the three Americans are going through.
