AlQa'dah 23, 1433, Oct 9, 2012, SPA - Swedish nuclear power officials say that police have arrested dozens of environmental activists who climbed fences to breach the outer perimeter of two atomic plants, AP reported. Greenpeace spokesman Daniel Bengtsson says 50 demonstrators swarmed the grounds of the Forsmark plant on Sweden's eastern coast on Tuesday. Some 20 activists sneaked onto the grounds Ringhals plant, which is in southwest Sweden. Officials said the inner, security areas surrounding the plants were not entered. The environmental group says it staged the action to demonstrate what it considers to be poor security at Swedish plants. In June, a small amount of explosives was found on a forklift at the Ringhals plant.
