Heavy snow shut down Paris' main airport for several hours and created travel chaos in Scotland on Wednesday, while in Spain a young boy's body was found after a flash flood. Flights in and out of Paris' Charles de Gaulle were suspended Wednesday afternoon, the city's airport authority said. When the airport reopened, only one of four runways was in use. At both Paris airports, flights were delayed by up to three hours. About 4 centimeters (2 inches) of snow quickly turned into a slushy mess in the streets of Paris, where heavy snowfall is unusual. All buses in the capital stopped running, as did many suburban buses, the city's RATP transit authority said. The Eiffel Tower was shut to tourists around midday, the monument's press service said. Officials said they can't sprinkle salt on the tower's floors because of concerns it could damage the iron monument. Simone Laloum, at work in a shoe shop near Paris' famous Champs-Elysees avenue, said she watched from inside as many people slipped and fell on the streets. "We are not prepared here for the snow in Paris, not equipped," she said. "People don't want to go out, they're scared of falling. It doesn't get cleaned up."
