PHOTOS: Kemboi wins third straight world title, gold for Hejnova

Zuzana Hejnova of the Czech Republic, the season's best performer, won the women's 400 metres hurdles beating American duo of Dalilah Muhammad and Lashinda Demus.

The Czech ran a personal best 52.83 to get the better of defending champion Demus. Muhammad edged past Demus near the end to take silver in 54.09.

The holder had to be contained with bronze with a timing of 54.27.

Hejnova was undefeated coming into the event and justified her favourite tag. 

Trinidad and Tobago's Jehue Gordon won his nation's first world championship gold for 16 years when he pipped Michael Tinsley to the world 400 metres hurdles title by a hundredth of a second in a lunging finish on Thursday.

Gordon's storming second 200 metres enabled him to mow down the fast-starting Tinsley right on the line, forcing the American to settle for silver again after his second place at last year's Olympics.

Gordon, the world junior champion in 2010, clocked a season-leading 47.69 with Tinsley (47.70) followed home by Serbia's Emir Bekric, who set a national record in 48.05.

Ato Boldon, who won the 200 metres crown in 1997, was Trinidad's last world gold medallist.

Sweden's Abeba Aregawi of Sweden won the women's 1,500 metres beating defending champion Jenny Simpson of the United States.

The Ethiopian-born Aregawi, who was only cleared to run for Sweden in December 2012, six months after receiving Swedish citizenship, clocked 4min 02.67sec, overtaking Simpson with 300 metres to go.

Kenya's Hellen Onsando Obiri took bronze in 4:03.86.

Ukraine's Bohdan Bondarenko of Ukraine cleared a meet record 2.41 meters to win the gold medal in the men's high jump.

Mutaz Essa Barshim of Qatar, the Olympic bronze medalist, improved to silver this time, clearing 2.38 while Derek Drouin of Canada took the bronze, also clearing 2.38.

Russia's Ivan Ukhov, the champion at London, finished fourth at 2.35.

Assured of the gold, Bondarenko then attempted to clear Cuban Javier Sotomayor's world record of 2.45m, set back in 1993, but failed in all his three attempts.

Caterine Ibarguen of Colombia won the women's triple jump ahead of home favourite Ekaterina Koneva.

Ibarguen, the silver medalist at the London Olympics last year, won with a world leading jump of 14.85 meters, holding off Koneva by 4 centimeters.

Olha Saladuha of Ukraine, the defending champion, took bronze with a leap of 14.65.

Ezekiel Kemboi won his third straight world title in the men's steeplechase, finishing ahead of Kenyan teammate Conseslus Kipruto.

Kemboi, who has also won two Olympic titles, won the race in 8 minutes, 6.01 seconds.

Kipruto took silver in 8:06.37 and Frenchman Mahiedine Mekhissi, a two-time Olympic silver medalist, took bronze in 8:07.86.

Kenya has won every world and Olympic title in the event since 2005 when Kenyan-born Qatari Saif Saaeed Shaheen took gold.
