A small civil plane has crashed in Co Waterford.
Multiple emergency service crews are responding to the incident near Tramore.
The crash occurred at about 12.50pm.
Multiple emergency service units including Coast Guard Rescue 117 are currently attending the scene, which happened on approach to Waterford Airport.
The R685 is partially closed and motorists are advised to use alternative routes.
Online flight-tracking websites show the privately owned Vulcanair P68C was flying between Sligo and Beziers, in France, when it turned around off the south coast of Ireland and headed back towards Waterford Airport before the crash.
An Garda Síochána confirmed the incident in a statement.
It said the crash involved a "light aircraft", while air crash investigators said it was a "twin-engined general aviation aircraft".
A spokesman said: "As this is a live and ongoing operation, no further information is available at this time."
The Air Accident Investigation Unit (AAIU) of the Department of Transport is investigating the incident with the emergency services and the Irish Aviation Authority.
The AAIU said it is deploying four air accident inspectors to the site near Lisselan, outside Tramore.
Sinn Féin TD for Waterford David Cullinane said a rescue helicopter was among emergency services responding to the crash.
He said it was a "shock" to the local area, adding that the community's thoughts are with whoever was on the plane.
