Iran’s Revolutionary Court found 28-year-old Amir Hekmati “Corrupt on Earth,” said the Fars news agency, and sentenced him to death “for cooperating with the hostile country . . . and spying for the CIA.” Under Iranian law, Hekmati has 20 days to appeal. His trial and death sentence came as Iran announced that it had enriched uranium at an underground facility and as the U.S. imposed harsher economic sanctions on Iran to stop its nuclear program…

Hekmati, an Arizona-born Iranian-American who served the U.S. Marines as a rifleman from 2001 to 2005, was arrested while visiting his extended family, including two elderly grandmothers, in Tehran on Aug. 29, 2011, according to the family. The family said they were urged by the Iranian government to keep quiet about his arrest with the promise of later release, but then in December, Hekmati was shown on Iranian television allegedly confessing to being an undercover agent of the Central Intelligence Agency on a mission to infiltrate the Iranian Intelligence Ministry.
