Yu Zidi started swimming at the age of six
Chinese schoolgirl Yu Zidi became the youngest swimmer in history to win a medal at the World Aquatics Championships as China claimed bronze in the relay.
The 12-year-old, who missed Thursday's final, swam in the heats of the women's 4x200m freestyle relay earlier this week and therefore qualified for a medal.
China finished third in the final in Singapore, behind the United States and winners Australia.
She is the youngest medallist at a major international competition since Denmark's Inge Sorensen won a bronze medal in the 200m breaststroke at the 1936 Olympics, less than a month after her 12th birthday.
