Flight operations at Dublin airport were briefly suspended due to the confirmed sighting of a drone over Ireland’s largest airport.
It is the first such disruption at an Irish airport.
Dublin airport told passengers on its Twitter page it suspended operations at 1149 GMT, before resuming 15 minutes later.
The flying of drones over Britain’s second-busiest airport, London’s Gatwick, sparked 36 hours of travel chaos last December while flights at Dubai International Airport were temporarily grounded last week due to suspected drone activity.
“We apologise for any inconvenience. Safety and security of passengers is always our key priority,” Dublin airport said on Twitter.
Ireland’s transport minister called a special meeting of the National Civil Aviation Threat and Risk Group last month to assess incidents at UK airports involving possible drone activity and the implications for Ireland.
Drones are prohibited from operating within 5 km of Irish airports during aircraft operations, unless the operator has permission to do so.
Transport Minister Shane Ross said appropriate action would be taken if further steps were required to improve response to the threat of illegal drone activity around Irish airports.
