Dubai inaugurates world's tallest 'twisted' tower
Dubai has inaugurated the world's tallest twisted tower built at a cost of $US272 million, setting yet another record for skyscrapers and other engineering marvels.
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 which came to its rescue during the financial meltdown.
