Investigators are trying to determine why a passenger train jumped the tracks in Spain, killing at least 78 people and injuring more than 140.
The government-owned train was traveling from Madrid late Wednesday when it derailed on a curvy stretch of track in Santiago De Compostela, located in the northwestern part of the country.
Alberto Nunez Feijoo, president of the region of Galicia, described the scene as Dante-esque.
"There are bodies lying on the railway track," he said.
Passenger Ricardo Montesco told radio station Cadena SER, "A lot of people were squashed on the bottom. We tried to squeeze out of the bottom of the wagons to get out and we realized the train was burning. I was in the second wagon and there was fire. I saw corpses."
Officials said the tragedy, which occurred as the city was preparing for a major Christian religious festival, was an accident and not an act of terror.
"July 24 will no longer be the eve of a day of celebration but rather one commemorating one of the saddest days in the history of Galicia," Feijoo said.
