A massive fire broke out Thursday night at the high-end Address hotel in downtown Dubai as New Year's revelers waited for a planned fireworks celebration in the United Arab Emirates' most populous city. Video showed orange tentacles of flames engulfing a large section of the high-rise hotel. Early reports from Dubai authorities said the fire started on the 20th floor of the 63-floor hotel. Jaqueline Hurtado, a CNN en Español correspondent, said she was at a restaurant in the area when she heard an explosion, "like a loud pop," and thought the fireworks display may have started early. "That fire was big. The fire was just going so fast," she said. "It just started burning real quick."
