Investigators suspect fire was result of deliberate act after reports that someone on board doused themselves in petrol
Police investigating a bus fire that killed at least six people in western Switzerland have said they suspect a deliberate act by a person on board but have for now ruled out a terrorist motive.
The vehicle, operated by a service to transport passengers and mail, went up in flames on Tuesday evening in Kerzers, a town of about 5,000 people 12.4 miles (20km) west of the capital, Berne, in the canton of Fribourg.
