American authorities reportedly refused an Air France flight from Paris to Mexico entry into US airspace because a left-wing journalist writing a book on the CIA was on board. Hernando Calvo Ospina, who works for Le Monde Diplomatique and has written on revolutionary movements in Cuba and Colombia , figured on the US authorities' "no-fly list". A spokesman for Mr Ospina's French publisher, Le Temps des Cerises, said: "Hernando, who was heading to Nicaragua to research a report, thus found out that he is on a 'no-fly list' that bans a number of people from flying to or even over the United States." Some 50,000 people are said to be on the list set up under George W. Bush, the former US president. The publisher accused the Central Intelligence Agency of being behind Mr Ospina's blacklisting, pointing out that the journalist was currently researching a book about the spy agency. "It shows to what degree its paranoia (has reached)," it said. Critics claim that [the list] has been abusively extended to peaceful critics of US policy.
