Three American hikers who have been detained in Iran after crossing into the country from Iraq have been charged with espionage, according to reports by Iran's State News Agency. Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27, have been detained in Iran since July 31. Their families say they entered the Islamic Republic accidentally while hiking in a scenic area of northern Iraq. The families, who have had no contact with the detainees, released videos in October that showed them dancing and singing before they were captured by Iranian authorities.
