What ship sunk by the french spies in 1985?

The ship that sank due to French spies in 1985 was the Greenpeace vessel, Rainbow Warrior. It was attacked in Auckland, New Zealand, by agents of the French intelligence service, who planted explosives on the ship to prevent Greenpeace from protesting against French nuclear testing in the Pacific. The attack resulted in the death of a crew member, Fernando Pereira, and significant international outrage. The incident highlighted the lengths to which governments might go to suppress activism and led to increased scrutiny of French intelligence operations.
