Protesters in a flotilla of six yachts in the South Pacific forced a ship carrying spent nuclear fuel from France to Japan to alter its course yesterday. Greenpeace spokesperson Elisabeth Mealey said the flotilla in the Tasman Sea off Australia had achieved victory by forcing the ship to make the effort to avoid them. The group says the ship is carrying enough plutonium to make 20 atomic bombs. One skipper in the flotilla said the protest movement was gaining momentum, with a local flotilla protest planned this weekend in Fiji.
