Phoenix Fire Department said their crews are on the scene of the incident, however there is no active fire, only smoke.
There is no information about possible casualties or the cause of the explosions, though media said electrical problems could have caused the fire.
Firefighters have blocked off the streets and sidewalks around the affected building. They said fire crews had responded to multiple reports of explosion at the hotel near 3rd and Van Buren streets.
The 31-storey building has been safely evacuated, the New York Daily News said. Hotel guests and employees were shown huddled together outside the building as some 100 firefighters in gas marks went in to investigate the source of the alleged blasts.
