A search is under way in the Derryveagh Mountains in Co Donegal for a missing walker.
The alarm was raised last night when the walker had not returned to his car which was parked at Loch Barra on the western outskirts of Glenveagh National Park.
It is understood he was walking in the Sliabh Sneachta area.
A coast Guard helicopter took part in the search for a time at midday today.
The Donegal Mountain Rescue Team is coordinating the search.
