A major search is under way for a hillwalker who has been missing overnight amid blizzard conditions in the Grampians.

Police Scotland said the 65-year-old male hiker was reported missing at 7.30pm on Friday.

He had failed to return from a walk on Lochnagar near Braemar, Aberdeenshire.

Braemar Mountain Rescue said a rescue helicopter had been hampered by blizzards and cloud.

Team members carried out a search on foot overnight alongside Aberdeen Mountain Rescue.

They reconvened at 7am on Saturday to continue the search at first light.
