The collision happened when one train derailed and crossed onto the opposite track before smashing into an oncoming train. Officials said the crash is the worst rail disaster Spain has seen in more than a decade.
Prime Minister Pedro Sánchez visited the site and announced three days of national mourning. He praised emergency workers and promised a full investigation to find the cause of the tragedy.

Transport officials said the derailed train was travelling from Málaga to Madrid. It left the track and struck another train heading from Madrid to Huelva, forcing several carriages into a nearby embankment.
Authorities said the cause of the derailment is still unknown. An official probe has begun, but findings are not expected for at least a month. The crash was described as “extremely strange” by the transport minister.
Spain’s rail operator Renfe ruled out excessive speed or human error. Its president said onboard safety systems should correct mistakes and suggested a mechanical fault or infrastructure failure may be responsible.
Around 400 passengers and staff were onboard both trains. Rescue teams continue working as twisted metal makes access difficult. Officials said identifying victims will take time.
