Passengers are experiencing delays and cancellations after an air traffic control outage led to the suspension of flights to and from Edinburgh Airport.
Services resumed at 10:40 after flights were grounded for about two hours, with some passengers reporting being stuck in planes on the runway.
There have since been knock-on delays, diversions and cancellations to flights in and out of the airport.
Edinburgh Airport said the problem had been caused by an IT issue with its air traffic control provider ANS, and thanked passengers for their "patience and understanding".
