A man has been arrested after a car crashed into the security barriers outside the Houses of Parliament. A number of people are also reported as having been injured.
The incident sparked a huge security incident and several streets around the Palace of Westminster have been cordoned off.
The driver was detained immediately following the incident after the car was swarmed by armed police who arrived promptly to the scene.
A Scotland Yard statement reads: "At 0737 hours today, a car was in collision with barriers outside the Houses of Parliament. The male driver of the car was detained by officers at the scene.
"A number of pedestrians have been injured. Officers remain at the scene. We will issue further info when we have it."
It is not yet clear whether the incident is terror related.
The area immediately surrounding the Houses of Parliament is protected by large steel and concrete barriers and is guarded by police at all times.
The security outside Parliament was stepped up in the wake of the attack on Britain's seat of government by Khalid Masood in March 2017.
Masood rammed his car into a crowd on nearby Westminster Bridge, killing four people. He then abandoned his vehicle and broke into a courtyard at the Houses of Parliament where he stabbed and killed PC Keith Palmer.
Khalid Masood was then shot dead by armed police in that same courtyard.
Metropolitan Police have since tweeted to say that they do not believe that any of those injured are in a life-threatening position. They also said that Westminster Underground Station is closed, as well as the cordons that are already in place.
