Flight operations at Dublin Airport have resumed after they were suspended this morning when a fire broke out in a hangar.
The fire has been contained and there are no reports of any injuries.
Daa said that due to the disruption passengers should expect some knock-on delays and are advised to check with their airline for the latest flight information.

Staff were evacuated from Hangar 3 after the fire broke out at around 7.15am.
Daa Communications Manager Siobhan O'Donnell said all people had been accounted for.
Thick smoke was seen billowing from the building by hundreds of passengers arriving for morning flights.
Air traffic controllers are hoping to clear the backlogs as soon as possible after flight operations resumed at around 8.45am.

Flight Radar 24 showed a number of planes circling the skies above Dublin this morning during the suspension.
Ten arriving flights were diverted, six to Shannon and four to Belfast, with around 40 flights affected overall.
Daa said its own crews were first on scene with other units from Dublin dispatched.
Ms O'Donnell said two whisper jets were in the hangar, but it is understood there was no damage to either aircraft, and said they would be fully inspected.
It is understood one of the short-haul 146 aircraft was operated by CityJet.

Ms O'Donnell said: "All flight operations were suspended because all emergency services have been brought to fight the fire and as a result if something happens on the airfield the fire cover is not available.
"This is standard procedure."

A spokesperson for Cork Airport said there had been no diversions there due to the disruption at Dublin.
Flights into Dublin are obliged to nominate a secondary airport, normally Belfast and in the case of transatlantic flights, Shannon.
