Iran reportedly detained seven US soldiers who were trying to enter the country on Sunday morning.The semi-official Iranian news agency Fars did not say where the incident took place, and had no further information.The BBC reported that there are no US troops usually stationed in the area, noting that the Fars news agency is "known to be close" to the Revolutionary Guards.Al-Jazeera also cited the Fars report, which added that "Two Iranians accompanying the troops were also arrested."The incident came as an American woman released from Iran after more than 13 months in custody began her journey back to the United States on Saturday. Sarah Shourd and two other Americans were detained in July 2009 along the Iraqi border. Iran has issued espionage-related indictments, which could bring trials for the two men and proceedings in absentia for Shourd. Their families say that if they crossed the border, they did so unintentionally.
