Meanwhile, the Sudanese government has charged a visiting American journalist with espionage. Paul Salopek, who won two Pulitzer Prizes as foreign correspondent for the Chicago Tribune, was arrested three weeks ago in Darfur. He’s in the region on a freelance assignment for National Geographic Magazine. He faces several years in prison. In a statement, Chicago Tribune Editor and Senior Vice President Ann Marie Lipinski said Salopek is “one of the most accomplished and admired journalists of our time… We are deeply worried about Paul and his well-being, and appeal to the government of Sudan to return him safely home.”
