TEHRAN (AFP) - The lawyer of two American hikers convicted of spying in Iran told AFP on Sunday their release on bail has been delayed since a judge whose signature is needed is on leave. "I went to the court asking them what is the latest and they told me that the second judge is on leave until Tuesday. So I am going there on Tuesday," Masoud Shafii said. "I am always an optimist and it will be over since the case is going through its natural and legal course," he responded when asked if he is expecting the case to be over soon.
