Three flights were diverted away from Dublin as a result, two traveling to Belfast International Airport and a third to Shannon.

No further sightings of the drone were reported and service resumed after 30 minutes.

This is the first time service at Dublin Airport has been affected by drone activity.

“This is something we would take very seriously and we will be carrying out an immediate review and will actively be involved in a wider review involving other State agencies,” O'Donnell continued.

It is illegal to fly a drone within three miles (5km) of Dublin Airport or any controlled airspace.

“I don’t think we should pretend that Ireland should be immune from challenges that are very difficult to deal with from a technical point of view,” Irish Minister for Foreign Affairs Simon Coveney said.

“There are sophisticated airports in some very well resourced countries that haven’t been able to deal with this issue easily, in the US and the UK most recently.”
