The Day 6 at Moscow worlds also saw three world leads in the other five finals in the evening session.

Caterine Ibarguen became the first Colombian woman to win a medal at the IAAF World Championships in Daegu two years ago who she took bronze in the women's triple jump. She continued to make history by becoming her country's first World champion, jumping a world lead equalling 14.85 to win the gold.

The Olympic silver medallist is unbeatable all year, winning at the Diamond League meetings in Shanghai, Eugene, Oslo and Paris.

Reigning world champion Olha Saladuha of Ukraine, who also reached 14.85 in June in Diamond League Eugene meet, was below par at 14.65 to settle with the bronze.

Russia's Ekaterina Koneva, who successfully defended her World University Games title in July with a PB of 14.82m, earned the silver at 14.81.

Jehue Gordon triumphed in a breath-taking home-straight duel against American Michael Tinsley, winning the men's  400m hurdles gold for Trinidad and Tobago with a world leading time of 47.69 seconds.

Tinsley clocked a personal best to 47.70 to take the silver while Emir Bekric trimmed Serbian national record to 48.05 to finished third.

Czech Zuzana Hejnova also clocked a world leading of 52.83 seconds to win in the women's 400 hurdles. Dalilah Muhammad of United States finished second in 54.09 while her compatriot Lashinda Demus notched the bronze with 0.18 s in arrears.

Kenya's Ezekiel Kemboi completed his world title hat-trick at 2013 IAAF World Championships, winning the third straight gold in the men's 3000 steeplechase.

The 31-year-old Kemboi, also a two-time Olympic champion, clocked 8 minutes, 06.01 seconds to secure the gold, albeit well shy of the world-leading time of 7:59.03 he set in Paris last month.

Kemboi successfully matched the hat-trick world gold feat of his legendary countryman Moses Kiptanui in the event, following his successes in Berlin and Daegu, respectively. It was also his sixth straight medal at a World Championships following consecutive silver medals at the 2003, 2005 and 2007 editions.

Conseslus Kipruto, also from Kenya but some 13 years Kemboi's junior, took the silver in 8:06:37. Mahiedine Mekhissi-Benabbad of France, a two-time Olympic silver medallist and 2011 World bronze medal winner, finished third in 8:07.86.

Abeba Aregawi claimed the first gold in Moscow worlds for Sweden as she clocked 4 minutes 02.67 seconds to win the women's 1500m race. The silver went to American Jennifer Simpson, who trailed 0.32 s behind. Kenya's Hellen Onsando Obiri pocketed the bronze medal in 4:03.86.
