Firefighters continue to tackle a blaze which broke out at midnight at Killarney National Park in Kerry.
The army helicopter has been called in to assist the fire service along with the National Parks and Wildlife Service and Kerry County Council.
The fire, which was fanned by a strong breeze, broke out deep in the park with the last fire being this severe in 1984.
Mayor of Kerry Cllr Patrick O’Connor-Scarteen stated, “This is absolutely shocking to see a fire so bad in the national park. The destruction of wildlife and habitat already is huge. The next few hours will be critical to see if it can be contained,”.
The helicopter is using water from the lake to douse over the fire.
The Department of Housing and Heritage has asked that people be cautious on the N71 as visibility in the area has been hindered by smoke.
