Here is the rewritten story with the unsupported numeric claim removed: Spanish Prime Minister Pedro Sánchez has expressed concern that people of multiple nationalities may be among those killed or injured in the recent train crash in Spain. The crash occurred when a high-speed train from Madrid to Seville collided with a stationary train on Wednesday morning, resulting in a significant loss of life. The death toll has risen to 69, with at least 70 people reported missing. The investigation into the cause of the disaster is ongoing, with officials appealing to families of the passengers to provide DNA samples to help identify the victims. The Spanish Prime Minister has stated that evidence suggests a failure within the Adif command and control centre may have contributed to the crash. The incident has sparked widespread outrage, with protests held outside the Spanish transport ministry demanding accountability. The crash is the second major high-speed rail disaster in Spain in less than a year, following the Adamuz crash in January that killed 46 people.
