500 Greenpeace activists from 20 countries create a human Rainbow peace symbol in the shadow of the Eiffel Tower to commemorate victims of terrorism. Twenty years ago two explosions sank the flagship, Rainbow Warrior and killed the photographer on-board, Fernando Pereira. To mark this anniversary, the original crewmembers and new activists pay tribute to a colleague killed and a boat bombed, in two ceremonies: one in Matauri Bay, New Zealand, and the other here in Paris.
