Two people have been rushed to hospital "as a priority" after a bus ploughed into a shop near Clapham Junction.
The crash left 10 people needing paramedic treatment and an air ambulance was dispatched to the scene in Lavender Hill, Battersea.
Emergency services from across London were called at around 6.55am on Thursday (August 10) to the junction with Altenburg Gardens after the double decker crashed into the front of a shop.
Two passengers who were trapped on the upper deck were cut free from the wreckage by fire crews, who have remained at the scene to help stabilise the shop.
Around 15 passengers evacuated the bus before the London Fire Brigade arrived, who sent two fire engines and three fire rescue units from across London.
A total of five ambulances crews, two paramedics, an incident response officer, and a hazardous area response team, along with the Metropolitan Police , also attended.
Crews from Battersea, Chelsea, Heston and Croydon fire stations attended the incident.
Road closures were in place.
Images on social media show the aftermath of the accident, with the shop front and front of the bus destroyed.
A London Ambulance Service spokesman said: "We were called at 6.53am to reports of a road traffic collision on Lavender Hill, SW11.
"We sent five ambulance crews, two paramedics in cars and an incident response officer to the scene, alongside our hazardous area response team - with the first of our medics arriving in six minutes.
"London's Air Ambulance was also dispatched.
"We treated a total of ten patients at the scene. Two of these patients, both in a stable condition, were taken as a priority to hospital.
"One patient with minor injuries was also taken to hospital for further treatment.”
Station manager, Ben King, of London Fire Brigade, who was at the scene, said: "This was a challenging incident in the early stages but crews worked hard to stabilise the shop and assist casualties alongside London Ambulance Service colleagues.
"The incident also involved some complex cutting to gain access to the upper deck of the bus so we could reach the two passengers who were trapped before lowering them to safety using an aerial ladder platform."
