The flames and smoke were stoked and debris fell from the 50th floor of the Trump Tower on Saturday night before firefighters could shut it down, according to firefighters and emergency officials.
An occupant of the building was seriously injured and taken to St. Luke's Hospital and placed in critical condition, FDNY Commissioner Daniel Nigro said during a press conference.
Four FDNY firefighters sustained life-threatening injuries, two of them related to burns, Nigro added.
They were part of another 200 firefighters and emergency workers battling the four-alarm fire at the 58-story Fifth Avenue Trump Tower on 57th Street in Midtown Manhattan, fire officials confirmed.
Nigro said the fire broke out around 5:30 p.m. and the fire trucks and the stairs were there in five minutes.
It was shot down in about an hour, he said. The FDNY declared the fire under control around 8 p.m.
At its height, the flames roared from the windowpanes when you could see pieces of ashen materials crumbling and falling from the glass skyscraper to the pavement below.
Firefighters were sweeping adjacent apartments and stairs to determine the source of the fire in one of the residential apartments of the skyscraper, according to firefighters.
There were no evacuations, although some residents left alone, confirmed Nigro.
The closure of several streets slowed the traffic of vehicles and pedestrians that surrounded the tower, from East 55th Street to East 57th Street from Fifth Avenue to Madison Avenue, according to authorities.
President Trump was not in New York this weekend.
Trump Tower, named after the 45th president, is also the headquarters of The Trump Organization and was the nerve center of the Donald Trump campaign when he ran for the Republican ticket in the 2016 presidential election.
This is the second fire that shoots up in the skyscraper.
Another fire on January 9, three people, including a firefighter, were injured after Secret Service agents detected flames from a heating and cooling unit located on the roof of the building.
The president maintains the top three floors of the building as his residential home.
He was in the White House on Saturday, very far from the fire incident.
The US Secret Service UU You have been informed of the incident, ABC has learned.
Trump praised the construction of the building as a "well-constructed building" and praised the firefighters who managed to put out the fire on Saturday.
"The firemen (and the women) did a great job, THANKS!"

The FDNY commissioner, Nigro, during a press conference also noted that the tower "sure got up quite well".
And like his father, Trump's son, Eric Trump, praised the first responders as "really some of the most incredible people in the world" to extinguish a fire "in a residential apartment."
