South Korea's Kim Yu-jin won the Olympic gold medal in the women's taekwondo featherweight (under 57kg) division, swiftly beating Iran's Nahid Kiyanichandeh in a show of strength for her country.
Kim's victory brings the number of gold medals in taekwondo at the Paris Olympics to two for South Korea, after Park Tae-Joon won gold in the men's taekwondo flyweight division on Wednesday.
South Korea had failed to win any medal at the previous Tokyo Games.
Kim defeated Kiyanichandeh in rounds, 5-1 9-0, a humbling score for the Iranian fighter, who holds the world title in her class.
Kiyanichandeh did not manage to get one kick through and lost six points over the two rounds in penalties, called Gam-jeom, while Kim secured victory with three kicks to the body and one to the head.
First-time Olympian Kim, 23, arrived ranked number 9 at the 2022 World Championship in her category.
Kiyanichandeh becomes the first Iranian woman to win silver at the Olympics in taekwondo, surpassing Iran's first Olympic medallist and former teammate, Kimia Alizadeh, who fled her homeland four years ago.
Kiyanichandeh defeated Alizadeh in the round-of-16, her first bout at the Paris Games.
Now fighting under the Bulgarian national banner, Alizadeh made it through repechage and secured a second bronze medal, the first Olympic taekwondo medal ever won by her new home country.
In an upset, the contest was also marked by the shock defeat of British two-time Olympic champion Jade Jones, who was ousted by North Macedonia's debutant Miljana Reljikj in the round-of-16.
Canada's Skylar Park won the other bronze medal.
