Flights have been diverted at Dublin Airport for the third time in four days after sightings of a drone on the airfield.
Four flights were diverted to Belfast, one to Shannon and one to Manchester as a result, Irish broadcaster RTÉ reported.
Flight operations were suspended for about 40 minutes and resumed at 19:45 local time on Monday, the airport said.
"The reckless and irresponsible behaviour of those causing ongoing drone disruptions is unacceptable," a statement added.
"Those found responsible will face prosecution."
It is illegal to fly drones within 5km (three miles) of the airport.
