The developer of a Dubai skyscraper set to become the tallest building in the world says the rising tower now stands at a "new record height" of 2,257 feet or 688 meters. Emaar Properties says the skyscraper - know as Burj Dubai - now has "more than 160 stories." Its exterior is almost done and work has started on the interior. The company's Monday statement gave no other details. The silvery steel-and-glass building's final height is a secret. Last summer, the developer announced the building surpassed Taiwan's Taipei 101 which has dominated the global skyline at 1,667 feet or 508 meters since 2004. In the four years of construction, Emaar twice postponed the skyscraper's finish, now slated for September 2009.
