A fire was reported on the 50th floor at Trump Tower in New York, the New York Fire Department said on Saturday, with one person having been killed by the blaze.
Shortly after 6 p.m. Eastern, social media video showed flames visible from the structure in the center of Manhattan.
Via Twitter, NYFD authorities confirmed it was a 4-alarm fire, but it didn't appear to spread beyond the immediately affected floor.
At least one person was reported to be dead, a senior law enforcement official told NBC News. Earlier, the fire commissioner said that the person was found in the 50th floor apartment where fire started.
President Donald Trump, who was in Washington, said on Twitter that the blaze was extinguished.
