(Reuters) – Investigations into spying allegations against three American hikers detained in Iran will be completed soon, Intelligence Minister Heidar Moslehi said in a news report on Saturday. Shane Bauer, Sarah Shourd and Josh Fattal were detained after they strayed into Iran from northern Iraq at the end of July 2009, further complicating relations between Tehran and Washington already deadlocked over Iran’s nuclear work. “Investigations about the three Americans will be completed soon. The result will be announced then,” Moslehi said in a report carried by Iran’s student news agency, ISNA. Iran has said the three Americans would be put on trial, without giving a date. They have not formally been charged with spying. President Mahmoud Ahmadinejad said in February that the three U.S. citizens may be swapped for the release of Iranians jailed in the United States.
