Two people have been injured, one seriously, after a fire broke out in the Trump Tower in New York.
About 84 firefighters were on the scene to battle the blaze, and video footage captured smoke billowing from the top of the luxury block.
Although local media initially reported that no-one had been hurt, the New York Fire Department later said one person had sustained potentially life-threatening injuries, and another minor injuries.
Footage from the scene showed a street packed with fire engines, and it was reported that 26 units attended the scene.
The 58-story Trump Tower, which houses apartments and office space, had been Donald Trump's primary residence before he became President of the United States last year.
Eric Trump, Donald Trump's son and the executive vice president of the Trump organisation, tweeted that the blaze had been caused by a small electrical fire in the cooling tower of the building's roof.
"The New York Fire Department was here within minutes and did an incredible job," he said.
