DUBAI, United Arab Emirates - Dubai opened the world's tallest skyscraper Monday, and in a surprise move renamed the gleaming glass-and-metal tower Burj Khalifa in a nod to the leader of neighboring Abu Dhabi — the oil-rich sheikdom that came to its rescue during the financial meltdown.
A multimedia presentation witnessed by Dubai's ruler and thousands of onlookers at the base of the tower said the building was 2717 feet tall.
