A high-speed train derailed and smashed into another oncoming train in southern Spain on Sunday, pushing the second train off the tracks and down an embankment in a collision that killed at least 21 people, said Spain's interior ministry, Reuters reports.
The accident happened near Adamuz in the province of Cordoba, about 360 km (223 miles) south of the capital Madrid.
Of the 75 people hospitalised, 15 are in serious condition, the chief of Andalucia's regional government, Juanma Moreno, told reporters early on Monday.
He said the death toll would likely be more than 20 and warned the number may rise by daylight.
"The forcefulness of the accident has been very strong ... we will likely find (more) corpses," Moreno said, adding that heavy machinery would be needed to remove the trains' wrecked metal pieces and try to locate any new victims.
Video from the scene shared on social media showed rescuers pulling passengers from twisted carriages lying on their side under the glare of floodlights. Some passengers climbed out of smashed windows, while others were wheeled away on stretchers.
El Pais newspaper reported that the 27-year-old driver of the Madrid-to-Huelva train, the one that was struck, was among the dead.
There were around 400 passengers on the two trains, most of them Spaniards travelling back to and from Madrid after the weekend. It was unclear how many tourists could be onboard as January is not holiday season in Spain.
"There are many injured. I am still trembling," Maria San José, 33, a passenger on the Malaga-to-Madrid high-speed train that first derailed, told El Pais.
A passenger on the second train, who was not identified, told public broadcaster TVE: "There were people screaming, their bags fell from the shelves. I was travelling to Huelva in the fourth carriage, the last, luckily."
The second train, heading to Huelva and operated by state-funded Renfe, was travelling at around 200 km per hour (124 miles/hour) at the moment of impact, reported El Pais.
It was unclear how fast the first train wastravelling when it derailed.
