NEW YORK  - Dozens of New York firefighters rushed to the World Trade Centre skyscraper early on Wednesday after a member of the public mistook welding for a fire. Initial reports from the New York Fire Department suggested a minor blaze on the 88th floor of One World Trade Centre, the centrepiece in the project to replace the Twin Towers destroyed in the September 11, 2001 terrorist attacks. A spokesman at first told AFP that there was a fire at the 104-storey building but that it had been brought under control in less than an hour. Subsequently the department downgraded the incident, saying that the 84 firefighters had been dispatched to the still unfinished tower.
