A 26-year-old woman has died after a crash between a car and a National Express bus in south-west London.
Both vehicles were engulfed in flames after the incident, which took place on Queenstown Road close to Chelsea Bridge in the early hours of Sunday morning.
The rear-seat passenger of the grey Volkswagen Polo car died at the scene and the female driver is in a critical condition, the Metropolitan Police said.
Footage from the scene, circulated on social media in the hours after the incident, shows both vehicles on fire.
Taken on Snapchat, police and ambulance crews can be seen trying to dampen the flames, which have engulfed both the coach and the car, and rescue people from inside.
Witnesses can be heard saying the vehicles “exploded” after they crashed into each other.
A spokesman for National Express said: “One of our vehicles on the A3 service from Gatwick to London Victoria was involved in an incident with a car on Queenstown Road in the early hours this morning.
“One passenger was taken to hospital and all other passengers were safely transferred to a replacement vehicle for onward travel.
“Emergency services attended the scene and we will continue to provide every assistance with the ongoing investigation.
“Our thoughts are with the family and friends of the occupant of the car, who sadly passed away.”
A London Ambulance Service spokesman confirmed that despite the “best efforts” of the crew, one patient had died at the scene.
“We took a second patient to a major trauma centre as a priority. We treated two further patients for minor injuries: we took one of them to hospital and the other was discharged at the scene.”
