Local police report the incident happened just after lunch when the Belgians were standing near a moraine at the side of the glacier, when a stone rolled off an incline where rubble had accumulated. A moraine is the collection of rubble carried along by the glacier.
The boy's family and bystanders alerted the emergency services that attempted to reanimate the boy, but in vain. The boy's family are receiving support. The daily Het Nieuwsblad says that the lad's remains are being repatriated this week.
