There was an explosion earlier today in the News Corp. building on Sixth Avenue. MyFoxNY reports that it was a chemical explosion (wha?) and that one man was burned. Over 700 people have been evacuated from the building. Gawker reports that there is smoke coming from the top of the building and that they are not letting anybody in. Also, “all the news photographers who can’t get into their offices are taking photos of the people standing outside!” That’s so meta. It’s like citizen journalism 2.0!
