Flights in and out of Cork Airport were delayed this morning after the airport was forced to close due to a drone flying in the area.
Gardaí are currently on site and are dealing with the matter.
A spokeswoman for the airport said that service has since resumed but aircrafts are approaching "with caution".
"There was a drone spotted in the airport and we had two aircraft on hold but now pilots have been told to come back in, obviously with caution".
The airplanes were forced to circle the airport and were unable to land during the incident after the drone was spotted at 9.45am this morning.
"Gardaí remain on the scene as they try to find the culprit," the spokeswoman said.
Cork Airport was the first Irish airport to launch a 'no drone zone' as part of a crackdown on rogue drone operators last year.
It is illegal to operate a drone within 5km of any aerodrome or within civil or military controlled airspace.
