Greenpeace activists with 'Stop Plutonium' banners outside French military base Cherbourg harbour, Cherbourg, France. Greenpeace activists protest against the imminent arrival of two BNFL (British Nuclear Fuels) ships, which are carrying 140kg of radioactive weapons-grade plutonium. The Pacific Pintail and the Pacific Teal left the U.S. port of Charleston on September 20th. Greenpeace believes the shipment conducted by the US and France is unnecessarily threatening international security and putting the environment at risk.
