A car collision near the Natural History and Victoria & Albert museums in London is not being treated as terror-related but a road traffic incident, according to police.
London Ambulance Service said it treated 11 patients, mostly for leg and head injuries, taking nine of them to hospital. Their injuries are not believed to be life-threatening or life-changing.
It said in a statement: "We have worked closely with other members of the emergency services at the scene, with our priority being to get people to safety and ensure they received the medical help they needed as quickly as possible."
The Metropolitan police said earlier a man had been detained, after an incident in Exhibition Road on Saturday afternoon, in the capital's museum district. The man is currently under arrest and is in custody at a north London police station.
Officers were called at 2.21pm to reports of a collision in South Kensington.
In an evening update, police said that while enquiries continue, it is believed a car mounted the pavement and collided with a number of pedestrians.
Details are still emerging and I have spoken with and am in close contact with Assistant Met Commissioner Mark Rowley and our other emergency services.
Police have asked people to avoid the area while their inquiries continue. Please follow @metpolice for further information.
Downing Street said the Prime Minister was being kept updated on the events, while Labour leader Jeremy Corbyn said on Twitter his thoughts "are with those injured" and thanked the emergency services.
