The Metropolitan Police's Counter Terrorism Command is now investigating the incident, the force has confirmed.
The incident happened at 7.37am prompting armed police to swarm the area. Ambulances and firefighters also responded, with streets around Millbank, Parliament Square and Victoria Tower Gardens cordoned off following the crash. Westminster Tube station remains closed.

A police spokesperson said: "Officers remain at the scene and cordons are in place to assist the investigation. Road closures in the area are likely to remain in place for some time. Westminster Tube station is currently closed.
"At this stage, we are treating this as a terrorist incident and the Met's Counter Terrorism Command is now leading the investigation.
