The US-based Carter Center, which sent a team to watch August's polls in Kenya, has said , externalthat its observers "publicly discussed concerns about the transmission of results" when they were there.

It noted that the Supreme Court suggested that the problem with the result was in the way they were transmitted to the election centre rather than in the voting and counting at the polling station.

The observer missions are fending off criticism after people had the impression that they had given the election a clean bill of health.

What they are all emphasising is that they said the vote itself went well and the problems came later.

One of the questions that has come up a few times today is - how come the international observer missions gave their stamps of approval for the Kenyan election, only for it to be declared null and void by Kenya's Supreme Court.

Earlier we reported that the Commonwealth observer mission's defense was that they were only judging the poll, not the count.

The Head of the Mission Marietje Schaake told BBC World News that they had flagged up issues with the count:

"We looked at the campaign and the days afterwards. As the tallying was going on and forms needed to be uploaded there were some challenges and those challenges."

She added that it was these challenges that are being tackled in court and she awaits the full judgement to see what evidence the Supreme Court has found.

President Uhuru Kenyatta has again criticised the Supreme Court judges for overturning the 8 August election, which the electoral commission had declared in his favour last month.

He was addressing an impromptu rally of supporters at a popular market in the capital, Nairobi, which was broadcast live by the privately-owned NTV.

“A few people have sat there thinking they know it all, but we have said, because we believe in peace and because we believe in the rule of law, let them say what they want,” Mr Kenyatta said, speaking in Swahili.

The president had earlier said the ruling went “against the will of the people”, but pledged to respect it.

He told his supporters:

Mr Kenyatta also said that the judges were “paid by foreigners and other fools”.

Commonwealth Secretary-General Baroness Scotland has said that "there is concern about how the technical counting may have taken place" after its election observers gave its verdict on last month's poll in Kenya.

She was responding on the BBC's Focus on Africa programme to the criticism that the Commonwealth's election observers had given the election their stamp of approval, only for the result to be declared null and void.

She pointed out that Commonwealth approval was given the day after the election so only referred to the poll itself.

She also urged caution to not make any conclusions about the count before the fuller judgement by the Supreme Court is released.

The decision by the Supreme Court of Kenya to annul the results of the presidential election and demand a new poll within 60 days is both good, and bad, for Kenya.

It shows the independence of the judiciary and its willingness to take controversial and unprecedented action despite a perilously short time frame.

But it also leaves Kenya in the same nervous limbo it suffered in the days following the election, while people anxiously waited for the results and what the losers’ reaction to defeat would be.

The country was paralysed because it has been down the road of contested elections before, and ten years ago it ended in bloodshed.

Most suspected some form of interference, intimidation and cheating in the election, but felt Uhuru Kenyatta’s wide margin of victory would be enough for the court to uphold the result.

But now it’s back to square one.

Events in Kenya have been moving fast since Kenya's Supreme Court annulled last month's presidential election result this morning.

Incumbent President Uhuru Kenyatta had been declared the winner, beating his main rival Raila Odinga by 1.5 million votes.

Here's a quick summary of events:

• The Supreme Court ruled by a majority decision that the election "was not conducted in accordance with the constitution and the applicable law rendering the declared result invalid, null and void"
• It said there were "irregularities and illegalities in the transmission of results" and these irregularities affected the integrity of the election
• The court found no evidence of misconduct on the part of Mr Kenyatta
• A new election has to be held within 60 days
• Mr Odinga's supporters celebrated in Nairobi and in his western stronghold of Kisumu
• Wafula Chebukati, head of the electoral commission, the IEBC, said he will not resign
• President Kenyatta said he respected the ruling even though he did not agree with it, asking how six judges can overturn the will of the people
• He also called for peace
• Mr Odinga said it was an unprecedented ruling in Africa adding that "Kenya is leading Africa as it so often does"

Today's decision by Kenya's Supreme Court is making news elsewhere on the continent as it's the first time an African opposition party has successfully challenged a presidential election result in court.

One of Uganda's leading papers has already put the ruling on the front page of its Saturday edition:

Kenyan opposition leader Raila Odinga is asking who will run the next election:

"There are more fundamental decisions to be made in the days ahead, including who will conduct the next elections."

"It is now clear that the entire IEBC [electoral commission] is rotten," he said.

"It is clear that the real election results were never shared with Kenyans. Someone must take responsibility."

He demanded criminal prosecutions and an inquiry.

Kenya's opposition leader Raila Odinga has said today's verdict "puts on trial" the international observers who "moved so fast to sanitise fraud".

He added: "Their role must be re-examined as it is highly politicised."

International observers praised the election in the immediate aftermath of the poll.

In today's decision, the chief justice said that President Uhuru Kenyatta was not involved in any fraud.

Kenya's opposition leader Raila Odinga has added to his speech about today's ruling, saying the Supreme Court is "setting this exceptional example for all of Africa".

"Our judiciary now knows they have the power," he added.

"We thank the Supreme Court for standing up for the truth."

Kenya's opposition leader Raila Odinga is speaking about today's Supreme Court ruling annulling last month's presidential election result.

He took the case to court challenging the result.

He said: "Never again will immunity reign again in Kenya.. a new Kenya has been born.

"Kenya is leading Africa as it so often does."

#SupremeCourtDecides is the big trending hashtag on Twitter in Kenya today as people digest this morning's ruling that annulled last month's presidential election result.

And in many tweets the panel of judges, in particular Chief Justice David Maraga, have been the subject of praise:

And today's events may have inspired some to get into the law:

But, of course, President Kenyatta himself has questioned how six judges can overturn the will of millions of people.

Raila Odinga will feel vindicated against accusations that he was just being a bad loser in challenging President Uhuru Kenyatta's win.

However, this historic decision is a massive indictment of the electoral commission. It is therefore no surprise that the opposition Nasa coalition is now calling for a new team to manage the next elections.

This is also a setback for the international, and some local, election observers, who praised the election as free, fair and credible.

People will be watching for the reaction of former US Secretary of State John Kerry, who was the head of the mission for US NGO, the Carter Centre, whose positive assessment of the election was used in court.

Regardless of the winners and losers following the ruling, this is a proud moment for Kenya. The litigation and debate on the merits of the election was done at the Supreme Court and not on the streets.

Chief Justice Maraga said it best in his opening statement: "The greatness of a nation lies in its fidelity to the constitution and the strict adherence to the rule of law."

Kenya's President Uhuru Kenyatta has said that, while he disagrees with the Supreme Court ruling that cancelled his victory in last month's presidential poll, he respects it.

But one of his lawyers is not so respectful - saying the decision was made by a "third world court" and that the judges were taking over:

If you are just catching up with the news that Kenya's election has been annulled, we've made this video to help you get up to speed:

President Uhuru Kenyatta has just reiterated his call for peace by tweeting:

Amani means peace in Swahili.

He repeated the word amani at least six times in his speech in the last hour.

He said earler that he did not agree with the decision to annul the election in which he had been declared the winner, but that he would respect it.

Kenyan shares, which rallied after Uhuru Kenyatta was declared the winner of the now-annulled election, tumbled today, prompting the authorities to suspend trading at the financial market in Nairobi for half an hour.

On Thursday, the Kenyan shilling had risen to a five-month high against the US dollar, driven by investors abroad trading in the local financial markets.

However today, the shilling weakened and Kenya's dollar-denominated bonds fell in value.

Business operations have generally continued uninterrupted, but there will now be a sense of caution and even anxiety about the impact on the economy.

Many businesses in Nairobi and other parts of the country closed in the days after the election last month over fears of possible protests. The renewed uncertainty will make them wary of trading in the next few days.

There is concern that foreign and domestic investors waiting to start new projects, or put more money into existing ones, might now hold back their funds, pending the outcome of the fresh elections ordered by the court.

The Kenyan Supreme Court ruling to annul the presidential election was made earlier by a majority vote.

But not all judges agreed - two of the six dissented.

We are taking a moment to look at exactly why they thought the election should not be annulled.

Lady Justice Njoki Ndung'u said:

Justice Jackton Ojwang said:

In the end, the majority decision was that the election was not conducted in line with the constitution and the results were declared null and void.

Chief Justice David Maraga said the full reasoning will be explained at a later date but in the meantime said:

Supporters of Kenya's President Uhuru Kenyatta have come out to support him in his home town Gatundo, north-east of the capital, Nairobi.

The election commission announced that Mr Kenyatta won last month's presidential election but that result has been annulled by the Supreme Court this morning.

One resident told the BBC's Peter Njoroge:

"The town is calm but with a sad mood".

They added that they came out in large numbers to support the president.
