The death of nine climbers - including three Britons - in the French Alps is the latest avalanche to claim the lives of mountaineers.
The avalanche occurred on Mont Maudit, which is the third highest peak in the Mont Blanc massif range.
According to local media, the dead also included two Germans, two Swiss and two Spaniards. It is understood 28 climbers from several countries were taking part in the expedition at the time.
