There was an intense fire on the roof of 515 West 34th Street earlier. WNBC has pictures and says that the flames were "several hundred feet" in the air. WNBC was streaming footage of the fire, which looks like it was put out, but damn, it looked crazy. The 12-story building is apparently a commercial building (right by the West Side rail yards), and it looks like there was a smaller structure on top.
WABC also has pictures and says that the fire could be seen as far away as Brooklyn. There were injuries, though the FDNY didn't say how many.
