At least 40 people have died and dozens more have been injured after two high-speed trains collided in southern Spain, local authorities have confirmed.
The incident near the city of Córdoba has been described by local officials as Spain's worst rail crash in over a decade.
Prime Minister Pedro Sánchez visited the scene on Monday, where he announced a three-day mourning period.
Here's what we know about the incident so far.
Where did the crash happen?
The crash occurred at around 19:45 local time (18:45 GMT) on Sunday, about an hour after one of the trains departed Málaga for Madrid.
The train derailed and crossed over to the opposite track, operator Adif reported.
It then collided with an oncoming train travelling from south Madrid to Huelva, which was forced into an embankment running alongside the track, according to Spain's Transport Minister Óscar Puente.
Most of the fatalities and injuries were from the front carriages of the Huelva-bound train.
What caused the crash?
The reason behind the train derailment remains unclear, prompting officials to launch an investigation, though it may take at least a month to deliver results.
Puente has described the crash as extremely strange, noting that experts are baffled by the circumstances of the accident.
Renfe's president dismissed the possibility of excessive speed or human error, attributing the incident to a potential mechanical fault or infrastructure issue.
Prime Minister Sánchez has expressed commitment to uncovering the cause of the crash while thanking emergency workers for their assistance during this tragedy.
Are people still trapped in the trains?
There were approximately 400 passengers and staff aboard both trains when the accident occurred. Authorities are still assessing whether anyone is trapped within the twisted carriages.
Córdoba’s head firefighter Francisco Carmona mentioned that rescuers have sometimes had to remove deceased individuals in order to reach survivors.
Who are the victims?
The 39 victims of the crash have yet to be identified as investigations are underway. As of the latest reports, 122 individuals have received medical treatment, with 48 still hospitalized, including five minors.
What have the survivors said?
Survivors on board described the impact as feeling like an earthquake, recalling a scene of chaos as noise, fear, and the force of the collision wreaked havoc inside the train.
“There were people screaming, calling for doctors,” shared passenger Salvador Jimenez, describing the devastating moment of the crash.
Rescue efforts continue as the nation mourns, and investigations unfold to discover what led to this tragic accident.
