Emergency services in northeastern Spain say nine people have been injured, three of them critically, in a dramatic bus accident at the mouth of a highway tunnel. The bus was carrying 50-60 textile workers. The bus appears to have hit the sloped edge as it was entering the tunnel and it was vaulted upward until its front came to a rest at the top. That left it propped diagonally across the entrance to the tunnel. Emergency authorities for the Catalonia region said two people were flown by helicopters to hospitals. A third critically injured person was evacuated in an ambulance.
