Reports: Iran Postpones US Hikers' Trial VOA News May 11, 2011 American hikers Shane Bauer (L) and Josh Fattal and their translator attend the first session of their trial in Tehran (File) Photo: Reuters American hikers Shane Bauer (L) and Josh Fattal and their translator attend the first session of their trial in Tehran (File) The trial for two U.S. hikers detained in Iran that was set to resume on Wednesday has been postponed. Swiss embassy officials say the proceeding has been delayed until an unspecified date because the two hikers were not transferred from prison to the courtroom. The Swiss embassy represents U.S. interests in Iran. Hikers Shane Bauer and Josh Fattal have been imprisoned in the country for more than 21 months on charges of spying. Iran has accused the two men and a third hiker of unlawfully crossing into Iran from Iraq in 2009. Tehran released the third hiker, Sarah Shourd, on bail in September. The trial of Bauer, Fattal and Shourd began in February. Shourd pleaded not guilty in absentia, and Bauer and Fattal also entered not guilty pleas. On Tuesday, the mothers of Bauer and Fattal told VOA Persian News Network they expect their sons to be found innocent of the charges and allowed to go home. Bauer's mom, Cindy Hickey, said other foreigners imprisoned in Iran have been released in a much shorter time span. She said the length of time the hikers have been in custody has taken a "devastating toll" on the families. Some information for this report was provided by AFP. .
