Roughly 84 firefighters responded to the scene initially.

"Although local media initially reported there were no injuries, one person sustained a serious, possibly life-threatening injury, and another had a minor injury, the Fire Department said," reports Reuters.

Eric Trump responded to the incident on Twitter.

“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!” he said.
