No tall tale: Dubai to open world's highest tower

Dubai is set to open the world's tallest building amid tight security on Monday, celebrating the tower as a bold feat on the world stage despite the city state's shaky financial footing.

But the final height of the Burj Dubai - Arabic for Dubai Tower remained a closely guarded secret on the eve of its opening. At more than 2,625 feet (800 meters), it long ago vanquished its nearest rival, the Taipei 101 in Taiwan. (AP)
