The 26-year-old Ethiopian-born Dutch runner romped home in a world leading championship record time of 3min 51.95sec to take gold at the Khalifa Stadium, with 2017 champion Faith Kipyegon of Kenya claiming silver and Ethiopia's Gudaf Tsegay taking bronze.

It was Hassan's second gold medal of the championships following her win in the 10,000m, making her the first woman to successfully double in the two events.
