[Firefighters are tackling a "major fire" in the
Slieve Donard area of the Mourne Mountains
in County Down for the second day.
The Irish Air Corp is due to assist fire crews
on Saturday afternoon.
Police have urged the public to stay away
from the area to allow crews to concentrate
on the blaze.
NI Secretary of State Brandon Lewis
asked people to heed this advice as
"deeply distressing scenes"
unfold in the area of outstanding
natural beauty.
The emergency fire operation was
escalated on Saturday morning.
The fire is on the lower slopes of Slieve Donard,
the Glen River Valley and Thomas Mountain.
Slieve Donard is the highest mountain in Northern Ireland.]
