At least six people died in a coach fire on Tuesday in a small town in western Switzerland, prompting the police to launch a criminal investigation.
Fribourg city police said the bus became engulfed in flames on a road in Kerzers, a town in the canton of Fribourg.
"At this stage, we have elements suggesting a deliberate act by a person who was inside the bus," said Frederic Papaux, a spokesperson for Fribourg police.
Three injured people were taken to hospital, the police added.
