At least 20 injured after train derails near Barcelona

It's Spain's second train accident in a matter of days.

Catalan officials say that the Rodalies train collided with a wall which had fallen onto the tracks between Gelida and Sant Sadurní, around 30 minutes outside of Barcelona.

This incident happened on Tuesday evening as heavy storms battered north-eastern Spain.

35 crews have been sent to the scene.

Of the 20 injured, at least four are believed to be critical.

The crash comes just two days after two high-speed trains collided in Andalusia resulting in the deaths of at least 42 people.
