Two Ryanair planes have clipped each other while taxiing on runways at Dublin Airport.
Minor delays to other flights were expected after the incident involving the Boeing 737 planes on Tuesday morning.
No injuries were reported after the "winglet" of one of the aircraft scraped against the tail of the other, a Ryanair spokeswoman said.
