Forty-six fire personnel are currently dealing with a “significant” gorse fire at Killeavy.
The Northern Ireland Fire and Rescue Service has also despatched six appliances.
It is believed at this stage the fire had been started deliberately.
An NIFRS spokesperson condemned these actions.
He said: “These incidents draw precious resources away from where they are needed most.
“Please support us by not starting fires deliberately.”
