In the shooting in Switzerland, 25 people needed medical treatment.

An ambulance was called at a personal event near Lake Zurich.

Although some people tried to walk on hot coals, the rites of passage are still used in various situations.

According to local police, 13 people were taken to hospital after treatment.

Others were treated at the scene and dragged into hiding.

It is not clear if the incident is part of a religious ceremony on the Au peninsula in Switzerland or a social incident.

Firewalking is often included in corporate and charity events.

It can be used by companies as part of team building exercises, including the UK.

A UK company offering internships says it helps most aspects of a company’s team building, motivation, change management or stress relief.

The investigation of the case is ongoing.
