Bolt arrives in South Korea

Usain Bolt - the world's fastest man - was welcomed by a throng of fans as he touched down for the IAAF Athletics World Championships in South Korea.

Locals at Daegu airport gave the world-record holding Jamaican a rousing reception on arrival, as he bids to reclaim the titles he won in Berlin in 2009.

Bolt, part of a 50-member Jamaica squad, is aiming to defend his 100m and 200m titles, but has warned he is unlikely to go close to the world-record times he holds.

The 24-year-old will also be part of the country's bid for a second successive 4x100m gold.
