It proved to be a successful final day of the event at the Ano Liosia Olympic Indoor Hall for Russian and Spanish taekwondo players, as both countries claimed two titles.

Aiukaev produced a stirring display to beat Isaev, winner of the gold medal in the category at last year's Olympic Games in Rio de Janeiro, 17-9.

Sajjad Mardani of Iran and Ukraine's Mykhailo Shelest were the recipients of the two bronze medals on offer.

Russia's second triumph of the day came in the men's under-74kg category as Maksim Khramtcov overcame Croatia's Toni Kanaet in the final.

Nikita Rafalovich of Uzbekistan and Serbian Damir Fejzic each took home a bronze medal.

While Russia swept the men's categories on the last day of action in the Greek capital, which hosted the 2004 Olympic and Paralympic Games, Spain dominated the women's divisions by topping the podium in both events.

Marta Calva Gomez ousted world champion İrem Yaman of Turkey in a hard-fought under-62kg final.

The Spanish taekwondo player demonstrated stern resilience as she battled to a tense 3-2 victory, while Yaman's team-mate Seyma Nur Sogut and Tulia Turutina of Russia earned bronze.

Castro Burgos Cecilia then followed Gomez's lead as she clinched top spot on the under-73kg podium with victory over Russia's Karina Zhdanova.

Turkey took both bronze medals thanks to Deniz Cansel and Sude Bulut.

Iran were the winners of the team trophy, which is decided based on results over the four days of competition.

Russia were second and Spain finished third.
