Jamaica's historic athletics win: Your views
Usain Bolt has become the first man to retain both Olympic sprint titles.
Bolt's team-mates, Yohan Blake and Warren Weir, won silver and bronze respectively in the men's 200m final.
Jamaica's Prime Minister Portia Simpson-Miller has praised the athletes. Thousands of jubilant Jamaican supports are celebrating on the streets of the capital, Kingston.
The BBC News website's Jamaican readers across the world have been reacting to the trio's momentous achievement.

The exact moment Usain Bolt and his team-mates crossed the finish line in first, second and third place was a cue for the crowds who had gathered in the city centre to erupt into spontaneous clapping and cheering. Everyone was euphoric.
There are celebrations planned for the duration of the Olympics and beyond. I had expected Usain Bolt to defend his title. He has achieved a double double victory. The 200m race is his speciality.
The nation is proud of all three athletes.
I knew Warren Weir would do something special... Now he is one to watch”
Yohan Blake is a phenomenal athlete. He is only 22 years old and this was his first Olympics. His remarkable performance has won him a silver medal.
I'm sure in the 2016 Olympics in Rio, he'll swap that silver medal for a gold one.
I knew Warren Weir would do something special. When he beat his competitors at the Jamaican National Championships and Olympic trials, everyone on the island took notice.
When he swept past the American competitor to win a bronze, the entire world paid attention. Now he is one to watch.
When the trio touch down in Jamaica we will give them a warm welcome.
That is the great thing about being from the Caribbean - we are naturally warm and welcoming.
Our Olympic athletes have been great ambassadors of this Caribbean spirit.

Strangers embraced and kissed and lots of people toasted our teams' success”
My parents are Jamaican, and although I am a British athlete I have strong Jamaican roots.
At least 900 jubilant Jamaican nationals watched the race at Jamaica House in North Greenwich Arena in London, England.
I was there too, accompanied by my family.
One can only describe the atmosphere as electric. It had spiritual undertones; each spectator willed the Jamaican team on and around the track.
We all had the same thought - that Usain Bolt needed an emphatic win to leave an indelible mark on the pages of Olympic history. It was gratifying to witness the realisation of our greatest hopes.
When Yohan Blake and Warren Weir crossed the line, it exceeded our wildest expectations. I tried to call my friend, former US sprinter Michael Johnson as he had correctly predicted the outcome of the race.
It was bedlam in the room, then it changed to a carnival atmosphere, much like London Notting Hill Carnival - only ten times better.
People were playing drums and other instruments, strangers embraced and kissed and lots of people toasted the team's success.
I had tickets to watch another Olympic event but I chose to stay at the Jamaica House, the atmosphere was just too good.

The atmosphere in my office was unreal. I had to watch the race several times to fully appreciate our historic one-two-three win.
My colleagues were hysterical when Usain Bolt crossed the finishing line, closely followed by his training partner Yohan Blake.
When Warren Weir came third, it sent the entire office into a frenzy. People began banging on furniture, cheering, slapping tables and filing cabinets.
The trio's dramatic win was an outstanding feat, one which has truly lifted the nation”
Even the most reserved employee stood up and cheered. Work ground to a halt. We were oblivious to our surroundings. Even our managers joined the celebrations.
The trio's dramatic win was an outstanding feat, one which has truly lifted the nation.
Before the race there was little doubt in anyone's mind that Usain Bolt would successfully defend his title. He rarely disappoints his fans.
It was truly heart-warming and inspiring to watch the experienced Usain Bolt take the young Weir aside just before the race and whisper some words of encouragement and advice to him.
The achievement of Bolt, Blake and Weir has shown the world that Jamaica can produce world-class athletes who are confident on the world stage and who can deliver under pressure.
I hope this will encourage our young children to engage with all forms of sport, not just athletics.
When all our athletes return, there must be a victory parade. A national holiday would allow Jamaicans to give the team a hearty, rapturous welcome.
Our heroic Jamaican Olympians deserve nothing less.

Sports bring people together and as Jamaicans we are proud of the entire team”
It was with great anticipation and nervousness that I waited for the start of the 200m race along with about 30 other coworkers.
We gathered in a small room around a television and waited with bated breath for the start of the race. When the race began everyone was screaming at the top of their lungs urging our three athletes on.
It was a wonderful feeling to see Usain Bolt win back to back 200m Olympic gold medal in London after he won the 100m.
A one, two, three victory was something I was hoping for but didn't think would happen, and for it to occur when Jamaica is celebrating its 50th anniversary of independence makes it even more special.
It couldn't have happened at a better time. It is something we won't forget for a long, long time.
Sports bring people together and as Jamaicans we are proud of the entire team participating at the games. The feeling of excitement still lingers.
