South Korea claimed all three gold medals on offer on day three of the World Taekwondo Junior Championships in Sofia as Palestine achieved their first medal at a senior or junior event.

The dominant nation of the day claimed the men’s under-55 kilogram, men’s under-59kg and women’s under-52kg titles.

Hong Euijun grabbed the first of the day after edging his tie against the United States William Cunningham 2-0 in the men’s under-55kg category final.

Niger’s Nouridine Issaka Garba and Kazakhstan’s Zhavokhirkhon Islamov both claimed bronze medals for their countries.

Seo Yeowon followed her compatriot to victory as she bettered Uzbekistan’s Marjona Khudaykulova 2-0 in the women’s under-52kg final.

Sara Spasojevic of Croatia and Anna Cuorvo of Italy jointly finished third.

Jung Woo-hyeok completed the hattrick of gold medals for South Korea as he beat Thailand’s Banlung Tubtimdang 2-0 in the final of the men’s under-59kg.

Palestine’s Omar Yaser Ismail and Alibek Shaikenov, also of Kazakhstan, both secured bronzes for their efforts.

Ismail's bronze means his country have now sealed a medal in World Taekwondo senior and junior competitions.

Action is due to continue in Sofia tomorrow.
