A Ryanair jet had part of its wing torn off after two of the airline's planes clipped each other at Dublin Airport.
The two Boeing 737s had been taxiing to the runway at the airport when the "winglet" of one of the planes scraped against the tail of the other, a Ryanair spokeswoman said.
Pictures taken by passengers on board show how part of the wing on one of the planes appeared to have become lodged in the tail of the other.
No injuries were reported although minor delays to other flights were expected following the incident this morning.
A Ryanair spokeswoman said: "Two of our aircraft were taxiing slowly to the runway at Dublin Airport this morning.
"The winglet of one aircraft appears to have scraped the tail of the other. There was no impact on customers on board."
Ryanair apologised to its customers for any inconvenience.
The Irish Aviation Authority confirmed it was investigating an incident involving two aircraft, during which emergency services attended the scene.
"The Air Accident Investigation Unit (AAIU) of the Department of Transport, Tourism and Sport has been notified and will conduct a further investigation," said a spokesman.
"Dublin Airport is now fully operational, although passengers may anticipate some delays as a result of this morning's incident and are asked to check with their airlines directly for further information."
