A French daredevil urban climber on Monday scaled the world's tallest building, the 828m Burj Khalifa in Dubai, fighting winds that delayed his ascent for hours.
Alain Robert, 48, who is also known as the French Spiderman, took about six hours to climb the more than 160-storey building, using a rope and harness as required by organisers.
But he said the safety precautions and the attention from a crowd that had gathered to watch made him more nervous.
"Actually there is huge pressure on me because I know that they have installed everything there; this is for me. There is a giant screen, 50m high, 30m long. I know everybody is going to look at me so it's a bit of - a lot of - stress in fact," Robert said before the climb.
