The accident occurred at 09.30 on Thursday when the car and the bus, which had no passengers, collided on Farstabron. The bus is gas-powered and the vehicles started to burn.

In the afternoon, the police announced that the car driver and the bus driver, both middle-aged men, had died in the accident.
