Azerbaijan's home European Games gold medal winner Iryna Zaretska continued a superb year by claiming gold on the second day of the World Karate Federation (WKF) Karate1 Premier League in Istanbul as Macedonia and Egypt each claimed team kata titles.
Zaretska claimed one of four Azerbaijani titles at Baku 2015, and continued this form by overcoming Viktorija Rezajeva of Latvia in the women's under 68 kilograms kumite final.
Titta Keinanen of Finland and Seyda Hafsa Burucu of Turkey shared the two bronze medals, while European Games silver medallist Alisa Buchinger of Austria had to be content with joint-fifth.
In the two team kata finals, in which squads of three athletes performed a specific variety of moves rather than spar with a rival, Egypt beat Iran in the men's final, while Macedonia got the better of Turkey in the corresponding women's event.
It was another day of Turkish success elsewhere, however, as another Baku 2015 medallist in silver medal winner Meltem Hocaoglu overcame Nathalie Reiter of Austria in the women's heavyweight over 68kg event.
Usda Aykut and Kaptan Ridvan secured a host nation double in the two heaviest male kumite sparring events, after winning the respective under and over 84kg divisions.
Aykut overcame Macedonia's Jakupi Berat in the final, while Ridvan got the better of Fioravante Valentino of Italy.
This put Turkey on eight gold medals overall, as well as four silvers and nine bronze, with no other nation winning more than a single gold.
Three more stages on the Premier League circuit are due take place later this year: in Hanua, Germany, on September 26 and 27, in Austrian city Salzburg from October 17 and 18 and in Okinawa, Japan, on November 28 and 29.
