 Greenpeace had planned to use the "Rainbow Warrior" as part of protest efforts over French nuclear testing at Moruroa, and DGSE divers sank the vessel by detonating mines against its hull while it was berthed in Auckland.The crew left the ship, but one person, Fernando Pereira, was drowned when he returned to a cabin to retrieve his cameras, just before the vessel sank.France initially denied responsibility for the attack, but later admitted its role.
