At least 119 people were killed and more than 150 injured when an Indian express train derailed in northern state of Uttar Pradesh on Sunday, with the toll set to rise amid a scramble to locate survivors.

Excessive speed is the most likely cause of a train crash in northwestern Spain which killed four people, the mayor of the local town suggested on Saturday.

German prosecutors Tuesday said human error was to blame for a train crash last week that killed 11 people and charged a 39-year-old signalling worker with negligence leading to the accident.
