LONDON (AP) — Police say an avalanche in the Scottish Highlands has killed two people and left a third in critical condition.

Emergency services responded to reports of an avalanche in the Cairngorm mountains that occurred around midday Thursday.

Police say a man and a woman who were airlifted from the Chalamain Gap area of the Cairngorms to Aberdeen Royal Infirmary have been pronounced dead.

Another man, who was flown to the same hospital, remained in critical condition, police added, saying the names and ages of the victims weren't immediately available.

Mountain rescue teams participated in the search, along with search and rescue dogs and the Royal Air Force.

Avalanches are not unusual in the area.
