New York City -
Firefighters responded to a fire alarm at the World Trade Center's 88th floor just before 8:00am this morning.
After responding, officials realized it was a false alarm and mistaken for someone welding. Steve Coleman, a spokesman for the Port Authority of New York and New Jersey, which owns the site, said the fire report was called in by a member of the public.
Last week the new WTC's 104th floor was being constructed with a beam lifted into place that was signed by President Obama.
