A number of Irish flights to London Gatwick Airport haven't taken off this morning after the airport was closed because of multiple drone sightings.
Two of them were spotted near the runway, disrupting flights to the airport and grounding outgoing ones.
Flights in and out of the airport were suspended at about 9pm on Wednesday after two drones were sighted near the airfield.
Gatwick announced that the runway had reopened at about 3am on Thursday – but just 45 minutes later it was shut again.
British police are investigating the incident, which has left thousands of people stranded just days before Christmas.
Some people reported being left stuck on planes for several hours while they waited to find out what was going on.
Gatwick advised anyone flying to or from the airport, or collecting someone, to check the status of their flight.
A spokeswoman added that airlines were working to provide affected passengers with hotel accommodation or transport for those whose flights were diverted.
