Athletics:Sanya Richards finally landed an individual global gold medal as she won the 400m at the World Championships in Berlin. The American, who has regularly flopped in major championships in the past, dominated the race to win in a world-leading time of 49.00secs.
Jamaica's Shericka Williams took silver in a personal best of 49.32, with Antonina Krivoshapka, of Russia, third in 49.71.
Britain's defending champion Christine Ohuruogu, whose preparations were hampered by injury, could finish only fifth, although she did set her best time of the year, 50.21.
Ezekiel Kemboi broke clear in a frantic last lap to clinch the men's 3,000 metres steeplechasegold medal and continue Kenya's domination of the event.
Compatriot Richard Kipkemboi Mateelong took silver with fast-finishing Frenchman Bouabdellah Tahri preventing a Kenyan clean sweep by pipping Paul Koech on the line for bronze.
Athens 2004 Olympics champion Kemboi, the only runner to crack the eight-minute mark this year, broke from a four-man pack 300 metres from the finish and held on to win in 8:00.43, a championship record.
Kenyan-born athletes have won the last 10 men's steeplechase world titles, though Stephen Cherono changed his name and nationality to win in 2003 and 2005 as Saif Saaeed Shaheen of Qatar, and also the last seven Olympic crowns.
Morocco's Jamel Chatbi withdrew from the event after testing positive in a doping test after the heats, the International Association of Athletics Federations (IAAF) said.
He is the first athlete to fail a drugs test in Berlin where the IAAF will carry out around 1,000 tests overall.
Britain's Phillips Idowu is the new world triple jumpchampion after a giant leap of 17.73m in the third round of the competition proved decisive.
Portuguese rival Nelson Evora denied Idowu gold at the 2008 Olympics but on this occasion he was unable to match the Briton.
Defending champion Evora claimed the early lead with a jump of 17.54m in the first round, Idowu responding with 17.51.
It was clear from the early stages that the big two were to dominate and despite regularly taking off from behind the board, Idowu managed to wrest the lead away from Evora in round three with an effort which was a new outdoor personal best.
The nerves were jangling as Evora stepped up for his final jump but the Portuguese could only improve his best effort by 1cm, which left Idowu to celebrate.
The Briton was in tears as he was confirmed champion before heading off on a lap of honour in the Olympic Stadium.
Cuba's Alexis Copello took bronze in 17.36.
Britain's other competitor, Nathan Douglas, finished down in 10th with his best effort of 16.79m seeing him eliminated at the halfway stage of the final.
Idowu becomes Britain's first male world champion since Jonathan Edwards won gold in the same event in Edmonton in 2001.
