More than 80 have been killed in a high-speed passenger train derailment in northwest Spain.
Stunning new surveillance footage shows the moment of derailment and now there is new concern about the cause.
The footage shows the train jumped the track as it was rounding a sharp curve, and there are early indications the train was traveling too fast.
“The scene is surreal,” reports CNN’s Karl Penhaul. “A packed passenger train approaching the Spanish city of Santiago de Compostela derailed as it hurtled around a curve.”
Its cars were left mangled and strewn around the track in the wake of the wreck; one snapped in half while another caught fire.
“Firefighters and emergency workers swarmed the scene, putting out the billowing fire and feverishly evacuating the train,” Penhaul says.
“In the dark, aided by flashlights, officials pulled injured and dead passengers through the windows, prying open doors to reach the most severely wounded.”
Hospitals are calling for blood donations to aid in the recovery as the death toll and number of injured continue to rise.
Meanwhile, an aide to the prime minister says they are pursuing all possibilities in the investigation into the cause.
And CNN has learned from a justice department spokesman that the driver is being questioned by police.
