French daredevil dubbed 'Spiderman' scales world's tallest tower in Dubai

A French skyscraper climber who calls himself 'Spiderman' has begun to scramble his way to the top of the world's tallest tower in Dubai.
Alain Robert began his ascent of the 2,717-tall Burj Khalifa just before sunset and said before he began that he expected his climb to take six or seven hours.
As night fell, a row of powerful spotlights shone on the side of the tower to light the way.
