American Simone Biles has become the first gymnast to win 13 world titles.

The 21-year-old won vault gold at the World Championships in Qatar.

It was her third world title in this year's Championships and she has now broken the all-time record set by Belarusian male gymnast Vitaly Scherbo in 1996.

On Thursday, Biles made history by becoming the first woman to pick up four all-around world titles after winning the team and all-around events.

The favourite for vault gold received a mark of 15.366 - ahead of Canada's Shallon Olsen and Mexico's Alexa Moreno.

She also picked up silver in the uneven bars - her first international medal on that apparatus.

Biles told BBC Sport: "I am very excited. I have worked especially hard on the uneven bars. I am proud of the outcome so far.

"The uneven bars medal is my favourite because I have worked so hard in that event."

The gymnast had not competed internationally since the 2016 Olympics, then on the eve of the Championships she was admitted to hospital with a kidney stone.

In January she revealed she had been sexually abused by a former Team USA sports doctor.

This was Biles 17th World Championship medal overall and she is three shy of the all-time record of 20, held by Russia's Svetlana Khorkina.
