Man climbs tallest skyscraper

A French man has climbed the world's tallest building.

Alain Roberts took six hours to scale the 2,717ft Burj Khalifa in Dubai.

The 48-year-old daredevil - who calls himself 'Spiderman' - used a rope and harness to complete the challenge.

He has climbed more than 70 skyscrapers, including the Empire State Building in New York and Taiwan's Taipei 101.

The tower's owner, Emaar Properties, called Robert's climb a "momentous" event and said the climber "scaled the exterior of the tower in a record-clinching feat".
