New York City fire officials say a fire in Trump Tower’s heating and air conditioning system injured two people and caused smoke to billow from the roof.

The FDNY says the fire started around 7 a.m. Monday at the building that contains President Donald Trump’s home and business offices.

No evacuations were ordered. Trump was at the White House when the fire broke out.

Fire officials say a civilian was treated for serious injuries and a firefighter was treated for minor injuries. It took about an hour to put out the fire on Fifth Avenue in Manhattan.

Eric Trump, the President’s son and an executive vice president at the Trump Organization, confirmed to the NY Daily News that the rooftop cooling tower ignited.

Eric tweeted his thanks to firefighters for doing “an incredible job.”

There was a small electrical fire in a cooling tower on the roof of Trump Tower. The New York Fire Department was here within minutes and did an incredible job. The men and women of the #FDNY are true heroes and deserve our most sincere thanks and praise! https://t.co/xuTmq1GBbj
