French 'Spiderman' scales Dubai skyscraper

Alain Robert, the French urban climber dubbed spiderman for his feats, has scaled the world's tallest building, the Burj Khalifa in Dubai.

It took him six hours to ascend the 828-m (2,717-ft) tower in the United Arab Emirates city, including the tapered spire above the top floors.

A large crowd watched from the ground as he moved up the facade, picked out by spotlights after darkness fell.

Unlike his many previous climbs, the 48-year-old used a rope and harness to comply with safety regulations.
