Firefighters are responding to a blaze at a Midtown high-rise office building.
The New York Fire Department said Friday morning that no injuries have been reported.
Five dozen firefighters responded to the fire on Madison Avenue a block from Grand Central Terminal.
The Fire Department did not identify a cause of the blaze, but a witness told WNBC-TV that workers evacuated the building after holiday decorations caught fire.
Authorities redirected traffic as onlookers posted videos to social media of flames and smoke pouring out of the front of the building near the street level.
