Police investigating a bus fire that killed at least six people in western Switzerland have said they believe it was started by a “marginalised and disturbed” Swiss man onboard who set himself ablaze.
The vehicle, operated by a service that transports passengers and mail, went up in flames on Tuesday evening in Kerzers, a town of about 5,000 people about 12 miles (20km) west of Berne in the canton of Fribourg.
