Residents in the western Swiss town of Kerzers gathered to pay tribute after a bus fire that killed six people.

Flowers and messages of condolence were laid near the scene where the blaze erupted on a bus travelling through the town’s main street.

Prosecutors said the fire may have been started by a man who doused himself with a flammable substance and set himself alight.

Authorities said there is currently no indication the incident was linked to terrorism.

Investigators are continuing to examine the circumstances surrounding the fire, which also left several passengers injured and shocked the small community.
