Irish Embassy pub on Bishop Street is closed and assessing water damage after a five-alarm fire broke out in the rooms above it early Saturday morning.

Irish Embassy's management posted a message on its Facebook page saying that they are still in shock following the incident.

"A severe fire broke out above the pub overnight. Our primary concern is of course the well being of our staff and anyone who was nearby, and we're glad to be able to say there were no injuries," read the statement.

The bar's management thanked customers for the outpouring of support online.

"We're still processing what has happened to our home, but we'd like to thank everyone who has been reaching out for their concern and kind words."

About 120 firefighters worked for hours to control the flames, which started around 5:20 a.m. on the third floor of the building.

No injuries were reported and no one was taken to hospital, but the adjacent buildings were evacuated.

While not registered as a heritage building, the building at 1234 Bishop Street was constructed in 1885.

Open seven days a week, the bar is popular among students and sports fans bound for the nearby Bell Centre.

The cause of the fire has not yet been identified.
