After reports of a fire at 1WTC, it appears to have been a false alarm, The Associated Press and others are reporting. FDNY firefighters rushed to the building, reportedly to battle a blaze that broke out on the 88th floor of the unfinished tower at 1 World Trade Center. Details are still scarce at this point, but NBC New York reports that more that more than 90 firefighters have responded to the fire that broke out around 7:45 a.m.

CNN cites a source at the NY/NJ Port Authority saying that about 84 firefighters responded to a call at the building, but that no fire was found. The New York Fire Department is still investigating.

CBS2's sky camera captured an image that appeared to show smoke rising over Manhattan, but (despite we originally believed) that image was showing a different area of the city. Their website reports that there was a small welding fire, but that it was quickly put out.
