The Economist tells a story they've obviously been sitting on for years, about Ahmad Batebi, an Iranian student who was pictured on their front cover in July 1999 demonstrating against the brutality of his own regime. He's been in jail ever since, until he recently managed to escape to Iraq, and from there reached the United States.
It's a story with a happy ending (Iraq is a better place to be than Iran, but the US is vastly better than both of them), but before the ending it's a story of relentless horror, real horror. The torture Batabi underwent is probably standard fare for Iranian prisoners - after all, he hadn't done anything particularly bad - but it's vastly worse than what the Americans and Israelis are routinely condemned for.
Update: the New York Times has a longer version of the story here.
