Still no word from Usain Bolt
after his meltdown in the 100m final but that is all for today's live commentary. Keep your eyes peeled on the
BBC Sport website
for the rest of the day as our team in Daegu will be filing all the latest reaction and analysis from an extraordinary day of action. In two hours' time we will have highlights of all the drama including Bolt and Mo Farah, while the live text commentary will return on Monday where the highlights include the men's 110m hurdles final and the women's 400m and 100m finals. Epic.
Kris on text, via 81111:
"I totally agree with the false start rule. People forget that going before the gun is a form of cheating. The old system resulted in too many false starts, done deliberately, to gain an advantage."
New 100m world champion Yohan Blake
: "I can't find words to explain it. Usain Bolt has been there for me. I feel like I want to cry. I've been trained by one of the best coaches but I stayed cool and caught him [Kim Collins]. I felt I would win the race for Bolt."
But now rule 162.7
states that "An athlete, after assuming a full and final set position, shall not commence his start until after receiving the report of the gun. If, in the judgement of the starter or recallers, he does so any earlier, it shall be deemed a false start. Except in combined events, any athlete responsible for a false start shall be disqualified."
As the calls for a change to the rules flood in, let's try and clarify the current situation. Previously athletes had been allowed one false start before being disqualified for a second, but new rules were introduced by the IAAF for the start of the 2010 season.
"Did Bolt feel he had a WR in him and therefore wanted to get a fast start? #bbcathletics"
: Drama everywhere you look in Daegu and amidst it all I neglected to bring you the results from the women's discus final. Apologies one and all. A win for China's Li Yanfeng who threw 66.52m, with Nadine Muller in second and Yarelys Barrios taking the bronze.
"Athletics is being ruined, in a stadium with that much noise and movement false starts will happen! #changethefalsestartrule #bbcathletics"
Dan from Oxford on text, via 81111
: "This rule on false starts is a farce. We want to know who is the fastest, not who is the most still in the blocks. Sort it out before 2012 or people are going to switch off. Athletics is in danger of losing its credibility."
What a dramatic session of athletics in Daegu. Not often that Dwain Chambers
will be able to console Usain Bolt
in his career, but now is that time. The fact that Bolt could have given the field several tenths of a second out of the blocks and still win will not ease the big Jamaican's peace of mind one bit. There is still the 200m to come for him though...
British 400m hurdler Dai Greene
"Crazy night of athletics, where do they get the script from?!"
Darren Campbell on BBC Radio 5 Live
: "It was a fantastic race but all the talk will be about Usain Bolt. That was a shock, pure and simple, but even the best in the world can get it wrong and the rules are the rules."
: Walter Dix pipped Collins on the line to take second for the United States.
: Kim Collins gets a great start to race out of the blocks but Yohan Blake
comes through in the second half of the race to take gold. A Jamaican champion but not the one we all expected.
YOHAN BLAKE WINS THE 100M IN A TIME OF 9.92 SECONDS 1247
: Incredible. Absolutely incredible. A huge false start as well from Bolt. He ripped his shirt off after just a few strides, he knew he had jumped the start. He cannot believe it...
USAIN BOLT FALSE STARTS IN THE 100M FINAL 1244
: The runners are being introduced to the crowd. Bolt strokes his beard, the calmest man in the whole stadium.
1242: Usain Bolt
was 25 last Sunday. In a little over two minutes he could cap a great week with his second world 100m title.
1240: Usain Bolt
is in the blocks getting warmed up. He looks, well confident and relaxed. But you knew that. The man oozes cool.
Former 100m world champion Tyson Gay on Channel 4
: "If you are racing Usain Bolt you can't worry about him running 9.58 seconds. Just concentrate on your own lane, get out well and run fast because if he gets ahead you are not going to catch him."
: The other runners taking on the challenge are Jimmy Vicaut, Daniel Bailey - no relation to Donovan - Walter Dix and Kim Collins.
: A Jamaican 1-2-3 looks the best bet for the 100m final as Yohan Blake
and Nesta Carter
battle with Usain Bolt
. Frenchman Christophe Lemaitre is also in the hunt for a medal.
1231: Trey Hardee
retains his decathlon title ahead of fellow American Ashton Eaton. Leonel Suarez of Cuba comes third.
: About 15 minutes to go until Usain Bolt
comes back out for the 100m. What sort of time are we hoping to see? Bolt's best time this year is a mere 9.88 seconds - practically a jog...
Former Olympian Steve Backley on BBC Radio 5 Live
: "It was a very deliberate strategy by Farah. He ran a 53 second last lap but had the legs run off him. He will only look at his strategy retrospectively and wonder whether he got it right."
: So we will have to wait and see if Mo Farah will go again in the 5,000m later this week. Understandably after that ordeal he needs a few days to recover. Mammoth effort from him, it all bodes well for London 2012 as well...
Mo Farah on BBC Radio 5 Live
: "It's agony and frustration, you always want gold but there's nothing you can do sometimes. I gave at my all but it wasn't good enough."
: Got lost a bit in all that drama there, but Ethiopian Imane Merga took bronze. Meanwhile, Brittney Reese
retains her long jump title with a jump of 6.82m.
"So proud of Mo. Ran with guts and intelligence. Be proud of yourself and take that tiny frustration into the 5k."
: Slow-motion replays really showing the anguish on Mo Farah's face there as he was overtaken in the dying stages. But Farah looks a bit more cheerful now, draped in the Union Jack, and he could still go again in the 5,000m yet.
Allison Curbishley on BBC Radio 5 Live
: "Mo did everything, he really did but Jeilan knew there was a slight opening of the door and once an athlete knows that they are buoyed. That was agony to watch. We have seen such a monumental rise in the last 12 months from this guy and he only has once place to go now."
"Gutted. Outstanding race from Mo, the first world medal a British male has ever won at 10,000m #differentgravy #bbcathletics"
1159: Mo Farah
slumps to the floor, what a heartbreaking way to miss out. But let's put that into perspective, a fantastic achievement to break the African stranglehold on the medal spots. He left nothing behind there in a gutsy run but he was just pipped.
: Stunning last lap in Daegu. Mo Farah
powered clear to open up a huge lead but was chased down by Ibrahim Jeilan
of Ethiopia who takes gold with a desperate overtake inside the last 10m.
MO FARAH WINS SILVER IN THE 10,000M 1159: Mo Farah
heads to the front down the home straight. There's the bell...
: Two laps to go. Farah still third...
: Attack from Martin Matathathi who ups the pace. Covered by Mo Farah, this is going to go to the wire. Three laps to go...
: Less than a quarter of the race left and Mo Farah
still looking good for a medal. His training partner Galen Rupp is right up there as well as they lap some stragglers.
1149: Zersenay Tedese
still leads with nine laps left, the field has been reduced to a group of nine and Farah
moves into fourth. Looking good.
: Incredible record from the Africans, and even more amazing is the fact that Kenenisa Bekele
has never lost a race at this distance. Until now - the Ethiopian steps off the track clutching his leg. One man down.
KENENISA BEKELE PULLS OUT
Allison Curbishley on BBC Radio 5 Live
: "Since 1991 the Africans have taken all the medals, 30 of them, Mo Farah will do something very special if he gets on the podium."
1144: Zersenay Tadese
attacks again but is covered by the leading group, with Kenyan giant Peter Kirui moving into the front. Farah still there in touch.
: There were a lot of question marks over Kenenisa Bekele's
fitness before this race but he looks in fine fettle to me. He's well up there as they approach halfway.
1140: Mo Farah
cruises to the front as they enter the last 16 laps. He's already ran nearly 4000m but looks as fresh as a daisy. Long way to go as the Kenyans converge at the front of that leading pack.
1135: Mo Farah
comfortably on the back of a leading pack of 10 or so athletes headed by Zersenay Tadese as they go through the first kilometre.
Paul from Vauxhall on text via 81111
: "The false start rule is a sham. Athletes train for years building up to big events and then can have their dreams shattered because of a twitch. Imagine if you had a high-paid job and then got fired for spilling coffee in the boardroom. Ludicrous."
No false start for Mo Farah
as he begins 25 laps of the Daegu circuit. A punishing run for all concerned - they will be out there for just shy of half an hour - and you can listen to the whole thing live on BBC Radio 5 Live with Mike Costello.
: Contrary to those earlier rumours Kenenisa Bekele
is out on track readying himself for the 10,000m final. Bekele is one of four Ethiopians in the race and there are three Kenyans out there as well. Let's not give Mo Farah
this gold medal just yet. He looks resplendent in his red and white spikes though - massive Arsenal fan don't you know. He fancied himself as a right-back in his youth, if Arsene Wenger sells any more players before the end of the transfer window he may be getting a phone call...
: Elsewhere in the stadium the women's long jump and discus finals are underway. Defending champion Brittney Reese
has had three fouls in the long jump so far but banked one good jump when it counts and currently leads.
: False starts galore in Daegu this weekend but at least Mo Farah
will be immune in the 10,000m, surely? Former 5,000m champion Bernard Lagat
is a big fan of Farah, he told Alex Capstick of the BBC World Service: "He's a hard trainer - if I were to train with him I would die - and also he has the best coach right now in Alberto Salazar."
Irish runner Joanne Cuddihy on BBC Radio 5 Live
: "To false start in 400m is just embarrassing. I don't know how that happened but I have full sympathy for Christine Ohuruogu now. I can't blame anyone but myself."
: No mishaps as the remaining seven athletes get under way. Amantle Montsho
from Botswana powers away to win in 50.13 ahead of Kapachinskaya. Sanya Richards-Ross scrapes through into the final as the second fastest loser. Lucky girl.
: Irish record holder Joanne Cuddihy
false starts in the third and final semi as former world 200m champion Anastasiya Kapachinskaya leads the field.
1106: Lee McConnell
finished seventh in 51.97 seconds. She tells BBC Radio 5 Live: "It's hard running blind in lane eight but I knew what I had to do. I held back too much and was too slow down the back straight."
: At 32, Lee McConnell is the oldest in her race but makes a strong start out in lane eight. By the halfway point though Francena McCorory
and Shericka Williams streak clear to take the top two spots. Sanya Richards-Ross was only third and will have to wait and see if she can make one of the fastest loser spots.
1100: Lee McConnell
is up in the second semi-final for Britain. World champion Sanya Richards-Ross is in lane four though and starts as favourite.
Marlon Devonish on BBC Radio 5 Live
: "Dwain is a pedigree athlete but it's so difficult to maintain your composure, it's very noisy in here, noisier than you think, and trying to maintain your focus is hard, you respond to the noise in the crowd and I feel for him because to go out to a false start is harsh. That's two Brits now and it's a nightmare."
1057: Allyson Felix
takes the first semi-final in a time of 50.36 seconds as Nicola Sanders comes home in sixth.
BBC Radio 5 Live pundit Allison Curbishley
: "The best thing for Christine Ohuruogu is she has another opportunity to come out. The 800m and 1500m runners don't but with the relay you get a second chance. I think they have an outside chance of a medal and I think this is what Christine needs. She was in so much shock and wanted to go out and run again. We have another chapter to the ever-growing book of Christine Ohuruogu."
: Women's 400m now. No Christine Ohuruogu
of course after her
false start yesterday
, but Nicola Sanders and Lee McConnell are in action for Britain.
1049: Harry Aikines-Aryeetey
edged out former Olympic champion Justin Gatlin to take third in that semi but it wasn't enough to make the last eight. There will be three Jamaicans in there though, with the final coming up at 1245 BST.
Dwain Chambers on BBC Radio 5 Live
: "The gun went and I moved before it fired. It was unfortunate, but it was enough, the rules are the rules, and I false-started."
1046: Harry Aikines-Aryeetey
left in the blocks as veteran Kim Collins
powers through to win in 10.06 ahead of Nesta Carter. No Brit in the final.
Third and final Brit Harry Aikines-Aryeetey
is ready to go in his semi-final now. Can he make the final?
Andrew from Nuneaton on text via 81111:
"Anyone like me think the rule that one false start is automatic disqualification is not helping the sport?"
Frenchman Christophe Lemaitre came through to take second and make the final. Marlon Devonish was seventh in 10.25
Just too easy for Usain Bolt
. Jamiacan Michael Frater got the best start but after 60m Bolt was miles clear. He has time to take a good look around before easing down to win in 10.05.
1037: Marlon Devonish
has an astonishing 20 major medals to his name. Usain Bolt
looks serene alongside him though, and has run nearly half a second faster over this distance. Let's not forget that world record in Berlin. 9.58 seconds
1035: Walter Dix
was second in that semi-final to qualify in a time of 10.05. Here comes Usain Bolt
though, flanked by Marlon Devonish.
A clean getaway from a British sprinter will be a good start...
BBC Radio 5 Live pundit Darren Campbell on BBC Radio 5 Live:
"It wasn't a false start, Dwain slightly twitched in the blocks and any movement at all is deemed as a disqualification."
Clean start this time and Jamaica's Yohan Blake
streaks away to win in 9.95 seconds. Very impressive performance from Usain Bolt's compatriot.
Drama in the 100m as Dwain Chambers
false starts. Two disqualifications in two days for British athletes. The sprinter falls to the floor in distraught mood. He only flinched in the blocks but it was clear to see.
DWAIN CHAMBERS DISQUALIFIED 1028: Dwain Chambers
is in the blocks for the first 100m semi-final. Can he make it through to yet another major final? Walter Dix looks his main rival in this race.
BBC Sport chief sports writer Tom Fordyce
"BBC hears from Bekele's agent Jos Hermans: Bekele WILL start. Altho Hermans jokes, "your man will still win". I think he was joking."
No worries for 800m world record holder David Rudisha
as he wins his semi-final to qualify in the quickest time of one minute 44.20 seconds.
Good news for United States sprinter Jeremy Dodson
, who is on his way to Daegu after a court hearing in Colorado on Friday following his recent arrest on suspicion of identity theft. Dodson qualified for the US team by finishing a surprise third in the 200m at the US trials behind Walter Dix and Darvis Patton.
BBC Radio 5 Live pundit Allison Curbishley on Andrew Osagie
: "That is such a shame because he was in all the right places and had all the right moves but did not have it in the last 100m. He is capable of running that time. He looks so disappointed."
Don't forget that you can get involved at any point with your views on Usain Bolt
and Mo Farah

1013: Andrew Osagie
tells Channel 4: "The three guys who beat me have all run fast so I can't be too disheartened. I need to lower my PB a bit for the rest of the year - that's the aim."
Strong run from Andrew Osagie
as he leads for the first 600m before being ran out into fourth place down the home straight. No place in the final for the Brit as Nick Symmonds takes the win for the United States.
Back on track and Andrew Osagie
is limbering up ahead of his 800m race.
For those of you just waking up, a round-up of the action from the
earlier session in Daegu.
qualified for the 400m semi-finals while there was disappointment for Brits Lisa Dobriskey
and Holly Bleasdale
First action on the track as 17-year-old Ethiopian Mohammed Aman
wins the first semi in the 800m ahead of Marcin Lewandowski.
So how good is Mo Farah? Former Olympic 1500m champion Seb Coe
has been on Radio 5 Live this morning and rates him as a 'world class athlete.' Coe said: "I think this year Mo has really come of age he has had a fabulous year. He has come here with the weight of expectation on him but I believe a medal would be great progresss for Mo. He has put himself into a category of a genuine world class athlete."
A bit of rumour and speculation coming in from Daegu which is encouraging for Mo Farah. Kenenisa Bekele
- who has won the last four world championships at 10,000m - is rumoured to not be racing later on as he battles through injury. That would be a huge boost to Farah's chances and we will confirm that as soon as we can.
First up on track in this session are the semi-finals of the men's 800m. Andrew Osagie
runs for Britain in the second semi-final.
Will Usain Bolt be in that final? Of course he will. Will he win? You'd think so. Will we see another world record? Now that would be nice. We will have to wait and see but the big man looked in
ominous form in yesterday's heat.
The top two in each semi-final go through to the final, with two fastest losers joining them for the showpiece event which gets under way at 1245 BST.
Usain Bolt runs in the second 100m semi-final at 1038 BST alongside Marlon Devonish
. Dwain Chambers
goes in the first race at 1030, while third Brit Harry Aikines-Aryeetey
is in semi number three at 1046.
If the prospect of a British gold medal isn't enough to excite you first thing on a Sunday morning, fear not, for the main man of athletics is also in action today - Usain Bolt.
Mo Farah races at 1130 BST where he will attempt to become the first British man to win a medal in the 10,000m at any world championships.
There is the real prospect of a medal for Great Britain's Mo Farah
this morning as he runs in the 10,000m.
Morning all, it's day two of the World Athletic Championships in Daegu and things are hotting up.
