There are some delays to departures at Dublin airport this morning due to an incident on one of the runways.
Ryanair has confirmed two of its planes clipped each other on the ground.
Arrivals are operating as normal.
The company says the aircraft were taxiing slowly to the runway when the winglet of one appears to have scraped the tail fin of the other.
They were both under Air Traffic Control instruction at the time.
Passengers have now been bussed back to the terminal and will board replacement aircraft for their journeys to Edinburgh, and Zadar in Croatia.
The airline's apologised for any inconvenience.
