Great Britain's Dai Greene has won the 400m hurdles gold medal in Daegu, Team GB's first of the championships.
The Welshman ran in a time of 48.27, finishing ahead of Puerto Rico's Javier Culson, who was ahead going over the last hurdle, and South Africa's LJ Van Zyl.
Greene, 25, told Channel 4 after the race: "I was disappointed that I was a little bit off the pace, but coming off the last hurdle I just had so much momentum. I just thought I can't let this go, this is mine."
Team GB now move up to fourth in the overall medal table, behind the United States, Russia and Kenya.
