Image source, EPATwo trains have collided in Spain causing at least 10 deaths, although there are concerns that the true number of casualties could be much higher (some reports are putting the death toll at 46).
The crash took place near the town of Urda, around 140 km (100 miles) south of Madrid.
Emergency services are at the scene helping those injured and looking for survivors.
The accident happened when a high-speed train travelling from Madrid to the south of the country collided with another train that was apparently stationary. The crash caused at least two carriages to fall down an embankment.
A passenger on board one of the trains told local media there was a heavy impact about 40 minutes into the journey.
Firefighters, paramedics and other emergency personnel are at the scene, along with three helicopters.
According to reports, the government believes that human error linked to signalling is a likely cause of the crash.
The national rail operator Renfe has set up a help line for relatives of those who were on board the trains.
And Parliament has cancelled events for the day. Prime minister Pedro Sánchez posted on social media that he was “upset” at the news and offered his solidarity and support to those hurt and their families.
In January, a collision between two trains on the same route killed 46 people.
