At least 21 people were killed and around 100 injured, including 25 seriously, after two high-speed trains derailed in southern Spain. The derailment occurred near the Adamuz area close to Córdoba, when a train traveling from Malaga to Madrid left the tracks, forcing another high-speed train on a parallel line to derail during an emergency maneuver. Rescue teams were dispatched to the scene as operations continued. Spanish Transport Minister Oscar Puente said the cause remains unknown, describing the incident on a straight, recently renovated line as unusual, and confirmed that an investigation has been launched.
