Elaine Thompson-Herah took gold in the women's 100 metres final to defend her title as Jamaica locked out the podium.

Thompson-Herah finished in a time of 10.61secs to set a new Olympic record and retain her crown ahead of two-time former champion Shelly-Ann Fraser-Pryce, with Shericka Jackson completing a 1-2-3 for Jamaica.

Cote d'Ivoire's Marie-Josee Ta Lou was fourth, 0.15 seconds off the bronze medal place, ahead of Swiss duo Ajla del Ponte and Mujinga Kambundji, while USA's Teahna Daniels was seventh.

Britain's Daryll Neita finished last after exceeding expectations to reach the final, setting a time of 11.12secs.

Thompson-Herah's time was the second fastest in history, beaten only by Florence Griffith-Joyner's world record of 10.49secs set back in 1988.

Jamaica had claimed two medals in each of the last two Olympic women's 100m finals, but this was a repeat of their podium lockout in Beijing, when Fraser-Pryce won the first of her titles ahead of compatriots Sherone Simpson and Kerron Stewart.
