This Police handout picture shows the accident site in the Gotthard tunnel, shortly after the fire broked out, Wednesday, October 24, 2001. At least ten people were killed in a head-on truck crash and fire in a major Alpine tunnel, but officials said safety features prevented a much worse disaster.
