Victoria underground station has been evacuated after a person was struck by a train.
The line has been partly suspended and emergency services are at the scene. The incident, which occurred at 10.30am, is not suspicious.
There had been reports of a fire at the station but a Transport for London spokesperson "unfortunately" confirmed a person was under a train.
Commuters caught up in the evacuation described people running for the exit "like there had been a terrorist attack".
A spokesman for the London Ambulance Service said: "We were called at 10.14am to Victoria Underground Station to reports of someone on the tracks.
"We sent a number of resources to the scene including an ambulance crew and our hazardous area response team."
