Multiple people have been injured after a car allegedly ploughed into pedestrians outside London's famous Natural History Museum.
Shocked eyewitnesses described how the vehicle "drove into people" near the museum, with victims seen being treated in the street.
Police confirmed a number of people had been wounded, although the extent of their injuries is unclear.
Dramatic footage appeared to show a man being pinned on the ground by security officers, with blood spattered on the street beneath his chin.
In the clip, he can be seen being held on the floor at the scene in South Kensington, west London, surrounded by members of the public and stationary vehicles.
