LONDON (AP) 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 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 crash happened at 2:20 p.m. on a day when the central London museum is usually teeming with pedestrians, including international tourists.
Photographs showed a dented silver car and a man being pinned to the ground outside the museum. It was not immediately clear if he was pinned down by police or others at the scene.
The London Ambulance Service was tending to the injured. There was no immediate statement on the number or severity of the injuries.
Shopkeepers in the immediate area were told to evacuate and police established a large security cordon around the area minutes after the incident, closing some roads. Police helicopters circled the scene overhead.
The Natural History Museum tweeted that there had been a "serious incident" outside the museum, which is located near the world famous Victoria and Albert Museum and other attractions.
Downing Street said British Prime Minister Theresa May was being briefed on the incident.
There have been a series of terror attacks on London and Manchester this year, including vehicle attacks on pedestrians at Westminster Bridge and London Bridge.
