UPDATE: Car incident in London Saturday not Terror related

London police say a car crash that injured 11 people outside the Natural History Museum is a road traffic accident, not a terror attack.

 Police made the statement Saturday afternoon nearly four hours after the car hit pedestrians in a crowded tourist area. One man was detained at the scene. He has not been charged.

The crash happened at 2:20 p.m. on a day when the central London museum is usually teeming with pedestrians, including international tourists.

The London Ambulance Service says nine people were hospitalized after the crash.

 Britain has been on a ``severe'' terrorist threat level and a massive police response followed the traffic incident.

The London Ambulance Service says 11 people in total were injured outside the Natural History Museum. Deputy Director of Operations Peter McKenna said Saturday that nine of the injured were taken to the hospital for treatment, most with leg and head injuries.

The incident caused panic on the crowded street outside the museum on Saturday afternoon.

McKenna said the service sent multiple resources including its hazardous response team to London's museum district.
