Jamaica have set a new championship record at the World Athletics Championships, completing the 4x100m relay in a time of 41.07s in Beijing.
Shelly-Ann Fraser-Pryce ran the anchor leg for the champions, surging away from her rivals on the finishing straight to secure the gold in the second fastest time in history.
The United States were in contention coming off the bench led by Allyson Felix, but had to settle for silver as Fraser-Pryce raced away in the closing metres, while the Netherlands also faded late on to slip back through the field.
Great Britain finished strongly to set a new national record of 42.10s, but Desiree Henry could not quite catch third-placed Trinidad and Tobago to secure a medal, finishing seven-hundredths off the podium.
