Espionage in Iran?

Three Americans detained in Iran several months ago have been charged with espionage, Reuters reports. Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27, had been arrested after straying into Iran from northern Iraq at the end of July. Their families say it was an accident. During an interview in September, Iranian President Mahmoud Ahmadinejad suggested that the release of Iranian diplomats being held by U.S. troops in Iraq might speed the Americans' release. Under Iran's sharia law, the crime of espionage is punishable by death.
