Train derails in Spain, killing at least 69

MADRID (CNN) -- A passenger train crash in northwestern Spain Wednesday killed at least 69 people and injured more than 100, a regional official said.

More than 20 injured victims remained in critical condition early Thursday, Agustin Hernandez Fernandez of the Galicia infrastructure ministry said

Investigators are looking at all possible causes of the crash, a senior aide to Spain's prime minister said Wednesday; their initial assessment is that it likely wasn't the result of terrorism.

Pictures of the scene showed at least one train car snapped in two and another one of the train's cars on fire. Rescue crews and fellow passengers pulled out bodies through broken train windows as stunned survivors looked on. Police escorted bloodied passengers from the wreckage.

State railway Renfe said the train derailed on a curve as it was approaching the train station in the city of Santiago de Compostela.

The high-speed train had 218 passengers aboard and was traveling from Madrid to the town of Ferrol in northwest Spain when it derailed at 8:41 p.m., the railway said.
