Activists display banners and flags with text, 'Stop Plutonium' during a protest at Pont Avignon, France. Greenpeace protests against the transport of weapons-grade plutonium, from Los Alamos USA, which will travel to Cadarache nuclear facility north of Marseilles. 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.
