NEW YORK - One person was killed and 4 firefighters received minor injuries in an apartment fire on the 50th floor of Trump Tower in New York on Saturday, in a blaze that was quickly extinguished, fire officials said.

The victim, a male resident, died at the hospital and has not yet been identified, they said.

US President Donald Trump, who has an office and a private residence in the midtown Manhattan structure, was not in the building at the time.

"Fire at Trump Tower is out. Very confined (well built building). Firemen (and women) did a great job. THANK YOU!" Trump tweeted.

Fire officials have not yet released a suspected cause of the blaze, adding no member of the Trump family was in the building at the time.

"This was a very difficult fire. As you can imagine, the apartment is quite large, we are 50 stories up. The rest of the building had a considerable amount of smoke," Fire Commissioner Daniel Nigro said on Twitter.

About 200 fire personnel responded to the incident that the department said was a 4-alarm fire.

Video on social media showed flames outside of a few windows and black smoke billowing up from the high-rise.

In January, 3 people were injured in an early-morning fire at the top of Trump Tower. One firefighter was hospitalized while 2 people received minor injuries that were treated at the scene, the New York Fire Department said.

In addition to the president's 66th-floor penthouse, Trump Tower houses the headquarters of the Trump Organization as well as other residences, offices and stores.
