Eight units of fire fighters are battling a blaze that broke out in a furniture store and has now spread to several adjoining buildings at North Main Street and Grattan Street in Cork city centre.
The alarm was raised just after 7pm this evening but the fire quickly spread to neighbouring buildings.
A spokesman for Cork's city fire service said it will take some time to bring the blaze under control.
All available units in Cork city are at the scene, including two hydraulic platforms.
It is understood that off duty fire-fighters are also being asked to report for work.
There are no reports of any injuries but traffic diversions are in place.
