Fire crews are continuing the fight to keep a wildfire from reaching America's premier nuclear-weapons laboratory and the surrounding community of Los Alamos. Firefighters spent Wednesday setting fires to create a burned out area west and south of the laboratory. The fire had grown to 201 square kilometres by nightfall. Officials say 13 homes have been lost so far and three others damaged. The pillars of smoke that can be seen as far as Albuquerque, 60 miles (97 kilometres) away, have people on edge. The fire has also cast a haze as far away as Kansas.
