DUBAI (Reuters) - Dubai's Emaar Properties said on Tuesday it has closed the observation deck at the world's tallest building for maintenance, just one-month after its fanfare opening.
Burj Khalifa, formerly Burj Dubai and renamed after the president of the United Arab Emirates, opened on January 4, as the emirate struggles with billions of dollars of debt.
