Spain seeks answers as high-speed train crash toll rises to 40

The death toll from a high-speed train collision in southern Spain rose to 40 on Monday as the government vowed a full investigation into its causes. The crash late on Sunday is Spain's deadliest train accident since 2013, when 80 people died after a train veered off a curved section of track outside the northwestern city of Santiago de Compostela.
