Greenpeace activists from Spain, Germany, Austria, and Italy boarded a nuclear-powered submarine from Britain today to protest its presence in Gibraltar, a British colony on Spain’s southern tip. The activists evaded Spanish police and British troops to reach the submarine, the Tireless, which has been docked in Gibraltar for nine months for repairs after a crack was found in its cooling system. Although officials say there is nothing to worry about, many of the 250,000 people living in the area fret that the sub may be releasing radiation. Elsewhere in Europe, Greenpeace activists are busy trying to prevent a second shipment of spent nuclear fuel from leaving France for Japan. The first shipment is headed around Cape Horn in South America, and Greenpeace, as well as the governments of Brazil, Uruguay, Argentina, and Chile, worry that the shipping route is too hazardous.
