An electrical fire has caused smoke to billow from the roof of Donald Trump's skyscraper on Manhattan's Fifth Avenue and has injured three people.
Reports claim that Trump Tower's heating, ventilation and air-conditioning (HVAC) system ignited earlier around 7am, but the New York City Fire Department tweeted saying the fire was "under control" shortly afterwards.
However, two civilians and a firefighter are said to have sustained minor injuries from the blaze, which caused a large plume of dark smoke. President Trump, who owns the building and keeps an apartment in the skyscraper, is currently in Washington DC.

Eric Trump, one of the president's sons and the executive vice president of the Trump Organization, referenced a problem with a cooling tower on the roof and praised the fire fighters swift response on Twitter.
Notoriously active on social media, Donald Trump has yet to comment on the incident, as of midday.
It is possible that the HVAC unit was overloaded, as New York City has experienced extremely cold temperatures over the past week ? the coldest spell to hit the area in decades in the aftermath of a winter storm referred to as a "bomb cyclone".
