A woman is in a critical condition after being attacked by cattle on an island in Lower Lough Erne, County Fermanagh.
It is understood the woman was walking her dog when she was attacked by cattle. The family pet later died as a result of injuries.
The Enniskillen RNLI crew, who were undertaking a training exercise, were called into action by the Coastguard.
The woman was assessed by paramedics and taken to the South West Acute hospital in Enniskillen.
The Irish Coast Guard took the woman by helicopter, along with her son who was uninjured, to the South West Acute Hospital, before she was transferred to the Royal Victoria Hospital in Belfast.
An RNLI spokesman said: "It was deemed that Rescue 118, Sligo's Coastguard helicopter, was needed to transport the lady.
"From what we've heard she was transferred to the Royal Victoria Hospital (in Belfast)."
A spokeswoman for the Department for Communities said: "The incident occurred on private land. The department is involved with discussions with relevant authorities and the landowner to ascertain exactly what happened."
It is understood the woman's injuries are serious, but not life-threatening.
