Authorities say a fire on the 88th floor of One Word Trade Center in New York is likely a false alarm.
The tower is the centerpiece of the construction at the site of the 9/11 attacks. The building is still under construction and is now the tallest in New York.
A spokesman for the Port Authority of New York and New Jersey, which owns the site, says the fire report was called in by a member of the public Wednesday and is believed to be a false alarm.
The report was thought to be related to welding at the tower.
The 104-story skyscraper is being built to replace the twin towers destroyed in the Sept. 11 attacks. It's expected to be completed in 2014.
