Two men out walking have died following separate falls in the Mourne Mountains in Co Down.
The fatal incidents occurred within an hour of each other in the Co Down mountain range.
PSNI Inspector Frances McCullough said: "Police received a request for assistance after a male was reported to have fallen while walking on Wee Binnian shortly before midday and received a further request for assistance after a male was reported to have fallen while walking on Slieve Commedagh shortly before 1pm."
Inspector McCullough said that police and other emergency services responded but "unfortunately both men died at the scene".
He said the deaths are not being treated as suspicious.
A third man was also rescued from the mountains with a suspected broken ankle following a fall close to the Saddle at around 2.30pm.
The PSNI's Air Support unit described the recovery and rescue operations as "tough and challenging".
A tough and challenging day in the Mournes as Police 46, @PSNINMDown and other emergency services responded to 3 separate incidents. In strong winds we managed to airlift one male out but sadly the two others had died. Our thoughts are with their loved ones.
