Fire breaks out at New York University's medical center
New York City's office of emergency management urged people nearby to close their windows and avoid the smoke, and warned of traffic delays near the area.
The blaze broke out at the Helen L. and Martin S. Kimmel Pavilion, which is under construction and scheduled to open in 2018, authorities told local media.
No injuries have been reported.
Images and video posted to social media showed plumes of black smoke and large flames ripping through the roof of the building on First Ave and East 30th Street.
