Part of Terminal 1 at Dublin Airport was evacuated for a short period before 8.30am on Monday morning when a fire alarm went off.
Pictures posted on social media showed crowds gathered outside the terminal building, with the fire service at the scene, as passengers advised each other to use security at Terminal 2.
However, Dublin Airport issued a statement saying its fire service “quickly brought the situation under control” and “security operations within [Terminal 1] remained open throughout and normal operations resumed shortly after 9am”.
A post on the global aviation news Twitter feed Air Live said: “Passengers arriving at Dublin Airport are reporting being evacuated from Terminal 1. Fire services are at the scene.”

In June, a fire in a ground handling vehicle was quickly extinguished within six minutes by the Airport Fire Service.
Most of the flights at the airport were taking off as normal on Monday with screens showing some delays for a small number of flights to destinations including Luton, England, Paris, France, and Toronto, Canada.
