Denver firefighters are battling a blaze that started in a building in the city’s downtown core.
At 10:35 a.m., firefighters were called to the 9th and 13th floors of the historic First American Bank building, which is located on the south side of the city.
A spokeswoman for the Denver Fire Department said that while they were initially able to extinguish the blaze, the flames grew to a large size and the fire department had to quickly call for additional resources.
The building’s exterior was completely destroyed, the spokeswoman said.
The fire started on the second floor of the building and moved through a hallway, where flames broke through the walls, and into the basement, the fire spokeswoman said in a statement.
The cause of the fire is under investigation.
