Late Saturday afternoon, firefighters were working to extinguish the fire at the soon-to-open Fontainebleau Las Vegas hotel and casino.
Aerial footage showed thick black smoke rising from the roof of the towering 67-story blue glass building. FOX5 helicopter shows off.
It is not immediately clear what caused the fire, or what damage it may cause to properties under construction.
Both the Clark County and Las Vegas fire departments were dispatched to the scene.

Construction on Fontainebleau Las Vegas began in 2007 and was originally scheduled to open in late 2009.
However, work came to a halt when the company went bankrupt during the recession, and the project stalled for years.
this is a developing story.
