There are delays to flights at Dublin Airport following a substantial fire at a hangar.

The blaze broke out in an air filtering unit early this morning and an emergency plan was put into action.

The fire was brought under control in around an hour.

Flights were suspended for a time and have since resumed - but there are some delays and passengers are being advised to check with their airline.

Four fire engines attended from Finglas, Kilbarrack, Balbriggan and Swords stations - while the fire crew based at the airport was also at the scene.

The blaze broke out in the roof of hangar three, which is used by aircraft maintenance firm Eirtech Aviation.

It is understood two planes were inside at the time for paint jobs, both of them short-haul 146 aircraft.

One of these is believed to have been operated by CityJet. They were not damaged by the fire.

In a statement, Eirtech confirms the fire was limited to a section of the roof and no one was injured.

The airport says the blaze was in a hangar in a restricted area separate from the passenger facilities.

The airport said in a statement: "Due to the disruption, there are likely to be knock-on delays to flights this morning and passengers are advised to check with their airline regarding their flight status".

Mobilisation Officer with Dublin Fire Brigade Mark Wilson says the scene will be handed over to the gardaí.
