Iran Executed U.S. Spying Scientist

Iran confirmed a report on Sunday that it executed Shahram Amiri, a nuclear scientist who gave the United States intelligence about the country's nuclear program. Amiri vanished in 2009 on a religious pilgrimage only to show up a year later in a set of online videos filmed in the United States. Amiri said he was kidnapped and held against his will by Saudi and American spies. It's not entirely clear what would have prompted Amiri's hanging years after he first disappeared.
