Greenpeace activists with police vehicles in background display flags and banners with text 'Stop Plutonium' outside the Cadarache nuclear facility, France. Greenpeace protests against the transportation of weapons grade plutonium originating from Los Alamos USA. The transport began in France after the arrival of UK-flagged commercial nuclear cargo ship, the Pacific Pintail, from Charleston USA. Before reaching its final destination it will have travelled more than a thousand kilometres across France, passing by numerous highly populated communities. Greenpeace believes the shipment is unnecessary and highly vulnerable to accidents or deliberate attack.
