A train has derailed in north-western Spain, killing at least 77 of its 218 passengers and injuring more than 100, officials in the Galicia region say.
All eight carriages of the Madrid to Ferrol train came off the tracks near the city of Santiago de Compostela.
Media reports say the train may have been travelling at more than twice the speed limit around a curve.
Officials have not commented on the cause. Analysts say it is the worst train accident in Spain in 40 years.
Spain generally has a relatively good record in terms of rail safety, says the BBC's Tom Burridge in Madrid.
This is a country which has invested huge amounts of money in its rail network, he says.
Spain's last major rail disaster was in 1972 when 77 people were killed in a derailment in Andalusia in the south.
