A French secret service diver who took part in the operation to sink Greenpeace ship the Rainbow Warrior 30 years ago has spoken publicly for the first time to apologise for his actions. Jean-Luc Kister ... was one of two divers serving with the French intelligence service, the Direction gnrale de la scurit extrieure (DGSE), who attached limpet mines to the hull of the vessel moored in Auckland in 1985. The Rainbow Warrior was heading for the Mururoa Atoll in the South Pacific in French Polynesia where France was planning a series of nuclear tests. French agents posing as Swiss tourists had earlier visited the ship ... to gather information for the operation. The first mine ... blew a large hole in the ship. Paris initially denied any involvement in the sinking, [which killed photographer Fernando Pereira], and described it as a terrorist attack". Documents released in 2005 and published in the Guardian, showed that France [also] tried to blame British intelligence for the sinking. The French government's responsibility, however, was quickly established. In 1987, under international pressure, France paid $8.2m damages to Greenpeace. It also paid an undisclosed sum to the Pereira family. Kister claims politicians in Paris turned down other suggestions for dealing with the Greenpeace protest. He said it was "an unfair clandestine operation conducted in an allied, friendly and peaceful country" ... and accused French politicians of "high treason" for having leaked his name and role in the operation after the sinking.
