Three-time world champion Walkden beat Germany's Lorena Brandl 22-7 in the women's over-67 kilograms final, while Williams claimed the women's under-67kg title after opponent Magda Wiet-Hénin of France pulled out injured when trailing 32-14 at the Italian city's PalaFlorio.

"I'm over the moon to win another title," Walkden, a Rio 2016 Olympic bronze medallist, told BBC Sport.

Turkey's Nafia Kuş and Serbia's Milica Mandić were the over-67kg bronze medallists.

The under-67kg bronze medals went to Croatia's Matea Jelić and Turkey's Nur Tatar Askari.

Today's other gold medallist was Russia's Aiukaev Rafail, who was crowned the men's over-80kg champion after Germany's Alexander Bachmann withdrew from the final.

Rounding off the podium were Slovenia's Ivan Konrad Trajkovic and Italy's Roberto Botta.

With taekwondo dropped from the European Games programme after the inaugural edition in Baku in 2015, the event in Bari aimed to compensate European athletes who would have otherwise missed out on the opportunity to collect ranking points for next year's Olympic Games in Tokyo.

"It was really disappointing that taekwondo wasn't included in the multi-sport event," Walkden told BBC Sport.

"But I'm glad we still had a competition and it's all experience ahead of the Olympics where I'm hoping to do bigger and better things."
