Idowu settles for silver
Britain's Phillips Idowu saw Olympic gold snatched from his grasp by just five centimetres in the triple jump.
Idowu produced his best jump of the year to lead with 17.62m after the third round, only to see Portugal's Nelson Evora power to 17.67.
Matching his PB of 17.68 would have given Idowu gold, but the 29-year-old Londoner was unable to improve, with fellow Brit Larry Achike seventh.
Idowu hurt by gold blow
Britain's Phillips Idowu admitted he was "upset and hurt" after seeing the gold snatched away by five centimetres in the final of the triple jump.
Idowu produced his best jump of the year with 17.62m, but he was beaten by Portugal's Nelson Evora.
He said: "It's not what I wanted but I'll take it. It was tough and really close in the end. It hurts and I'm upset that I fell just short."
GB disqualified in relay
Great Britain will not be able to defend their Olympic 4x100m men's relay title after being disqualified.
The British quartet of Tyrone Edgar, Simeon Williamson, Marlon Devonish and Craig Pickering finished second in their semi-final behind Jamaica.
But Pickering went off too early on the final change and only got the baton from Devonish after running outside the changeover box down the home straight.
Gold for Campbell-Brown
Pre-race favourite Veronica Campbell- Brown continued Jamaica's superb form in the sprints when she successfully defended her 200m women's title.
Campbell-Brown came home in a lifetime best 21.74sec, with American Allyson Felix having to settle for silver - as she did in Athens in 2004 - with 21.93.
Jamaican Kerron Stewart claimed the bronze medal after four previous sprint golds for the Caribbean island.
Sayers misses a medal
Great Britain's Goldie Sayers missed out on a medal in the women's javelin.
The 26-year-old finished fourth, 0.38m behind Germany's bronze medallist Christina Obergfoll, after a personal best and British record 65.75m throw.
There was disappointment for Michael Rimmer, who failed to qualify for the 800m final, while defending champion Yuriy Borzakovsky, of Russia, missed out after a poor run in the heats.
Dobriskey makes final
Commonwealth champion Lisa Dobriskey reached the final of the women's 1500m, but GB team-mates Stephanie Twell and Susan Scott both missed out.
Dobriskey was third in the final heat to secure automatic qualification with a new personal best of 4min 03.22sec.
Twell could manage only sixth in her heat and Scott fourth after a very slow second heat to miss out on the three places available to fastest losers.
IOC boss criticises Bolt
IOC president Jacques Rogge has accused Jamaican star Usain Bolt of showing a lack of respect to other sprinters.
Rogge is unhappy with the double gold medallist's celebrations, particularly his gesturing before even finishing the 100m in which he set a new world best.
But Rogge told The Times: "I understand the joy - but the way it was perceived was 'catch me if you can'. You don't do that. But he'll learn."
Bolt earns Johnson praise
Michael Johnson believes Usain Bolt has taken his place among sprinting's greats by setting another world record.
Bolt won the 200m in 19.30sec, 0.02sec quicker than Johnson's previous mark, and the American expects the Jamaican to lower both sprint records further.
Johnson told the Daily Telegraph: "He doesn't just want to win, he wants to test the limits of human ability. There is still much more to come from Usain."
Awde struggles early on
Britain's Daniel Awde has continued to drop further down the decathlon field as torrential rain soaked the stadium.
Awde followed up his seventh place in the 100m heat and 7.12m best in the long jump with a best of 12.03m in the shot put, dropping him to 31st.
American Bryan Clay continues to lead but Ukrainian Oleksiy Kasyanov used his 15.15m throw to move into second place ahead of Clay's team-mate Trey Hardee.
Blonska set to learn fate
Ukrainian heptathlete Lyudmila Blonska will learn today if a positive drugs test has ended her Olympic career.
It was announced on Wednesday that the silver medallist had failed a dope test for the second time in her career and had been "removed from the Games".
Anti-doping authorities will test the 'B' sample today and if the positive test is confirmed Blonska could be given a lifetime ban.
Jackson targets London
Great Britain's Johanna Jackson has already set her sights on the London Olympics after finishing 23rd in the women's 20km walk in rain-soaked China.
The 23-year-old from Middlesbrough set a new British record of 1hr 31min 33sec in finishing just over five minutes behind winner Olga Kaniskina of Russia.
Jackson said: "I've got a lot more to go in my training and hopefully I can challenge in four years' time."
Leeflang slams 'petty' US
The Dutch Antilles' minister for sport has accused the US of petty behaviour following the men's 200m final.
Having seen Wallace Spearmon denied bronze for running out of his lane, the US reported second-placed Churandy Martina for the same offence, meaning two Americans were bumped into medals.
Omayra Leeflang said: "It's not in the spirit of the Games. It's a pity for a big country to make a small statement."
Martina ready to move on
Churandy Martina has vowed to "come back harder" after being stripped of his silver medal in the men's 200m.
The Dutch Antilles sprinter was deemed to have run outside his lane and was disqualified after protests from USA.
Martina said: "I stepped on the line and they saw it. It's bad for me but I've got to move on. I'm sad to lose my medal but I know what I'm capable of so I'm going to practice and come back."
