Algerian boxer Imane Khelif defied a major gender controversy to win gold at the Paris Olympics on Friday in front of a pulsating Roland Garros crowd that roared her to victory.
Khelif claimed a unanimous points decision win over China's Yang Liu in the women's 66kg final for her first Olympic medal.
Taiwan's Lin Yu-ting, who together with Khelif was disqualified from last year's world championships after failing gender eligibility testing, fights in the women's 57kg final on Saturday.
There were large numbers of Algerian fans at the 15,000-seated Court Philippe Chatrier, usually home to Grand Slam tennis but instead there to witness one of the most controversial athletes at the Games.
Standing 1.79 metre (5ft 9in), Khelif had enjoyed a height and strength advantage over the three opponents she comfortably dismantled on her way to the final.
Yang was a different proposition, the 32-year-old being nearly as tall and also having pedigree as a world champion.
Loud cheers went up when the 25-year-old Khelif entered the arena, shadow-boxing her way towards the ring as chants of "Imane, Imane" rang out.
Khelif dictated most of the first round from the centre of the ring and unloaded a flurry of punches on Yang two-thirds of the way through to take the early initiative.
The second round started in the same way, with Khelif's punches appearing to carry more snap, power and menace.
The Algerian was ahead on all the judges' scorecards heading into the third and final round, and she just needed to avoid serious trouble to claim gold.
The two embraced at the bell, and after Khelif's comprehensive victory was confirmed, she was paraded around the arena on the shoulders of an Algerian team member.
Khelif and Lin both fought at the Tokyo Olympics three years ago but there was no controversy at the time and neither won a medal.
Both were thrown out of last year's world championships, which was run by the Russian-led International Boxing Association (IBA), but were cleared to compete in Paris.
The International Olympic Committee (IOC) has overseen the sport at the Games because of concerns over the IBA's running of boxing, including questions over its finances, ethics and judging of bouts.
The gender controversy ignited in the French capital when Khelif defeated Angela Carini in 46 seconds in her opening bout, the Italian reduced to tears and abandoning the fight after suffering a badly hurt nose.
The IBA's Kremlin-linked president Umar Kremlev claimed at a chaotic press conference this week that Khelif and Lin had undergone "genetic testing that shows that these are men".
The IOC has leapt to the defence of both boxers, with president Thomas Bach saying they were born and raised as women, and have passports saying that.
Neither is known to identify as transgender, and they have enjoyed strong support back home.
