France train shooting: 'I didn't know my injuries were that bad'

The three US men who helped to subdue a gunman on a train in France have been speaking for the first time about what happened.

Spencer Stone, Alek Skarlatos and Anthony Sadler appeared at a news conference at the US embassy in Paris.

Mr Stone said the attacker kept pulling out more weapons and jabbed at him with a blade. He then explained how he went to the aid of another passenger who had been shot.
