In 1985, the French nuclear weapons tests at Moruroa in the Pacific Ocean was being contested by environmental protesters led by the Greenpeace campaign ship, "Rainbow Warrior". The Action Division of the French Directorate-General for External Security devised a plan to sink the "Rainbow Warrior" while it was berthed in harbor at Auckland in New Zealand. Two divers from the Division posed as tourists and attached two limpet mines to the ship's hull; the resulting explosion sank the ship and killed a Netherlands citizen on board. Two agents from the team, but not the divers, were arrested by the New Zealand Police and later convicted of manslaughter. The French government finally admitted responsibility two months later.
