Kenya’s national elections last Tuesday were closely watched around the world, less for the results than for the threat of violence that has marred past elections. Barack Obama, whose father was a Kenyan, had been among those urging the country’s leaders to “reject violence and incitement.”

That has not happened. Raila Odinga, a perennial loser, began crying foul long before the election commission declared that President Uhuru Kenyatta was re-elected with 54 percent of the vote to Mr. Odinga’s 45. Mr. Odinga’s unsubstantiated claims have already touched off rioting in parts of the country, and the violence could spread.

That is disgraceful and unnecessary. International monitors from the African Union, the United States and Europe said they witnessed no foul play; former United States Secretary of State John Kerry, co-leader of the Carter Center’s mission of election observers, praised Kenya’s election commission for its transparency and diligence. All observers have urged Mr. Odinga and other losing candidates to refer any allegations of fraud to the commission and the courts.

Mr. Odinga’s specific claim is that Mr. Kenyatta’s Jubilee party hacked into the election commission’s computers to manipulate results, using the identity of Christopher Chege Musando, the commission communications manager who was murdered a few days before the voting. His death remains unsolved. The commission said that there was an attempt to hack the computers but that it failed.

All that can and should be checked. But in the meantime it is imperative that Mr. Odinga strongly urge his followers to remain calm. At 72, he might mull the idea that a display of respect for the new Constitution would be a far better legacy than another bloody spasm of violence.

Diplomats and regional leaders are presenting a united stance in urging Odinga, a former political prisoner, to concede.

"I want to congratulate Uhuru Kenyatta," Federica Mogherini, foreign minister for the European Union, which did over $3 billion worth of trade with Kenya last year, said.

"In line with the African Union, the EU expects the opposition to respect the results and to use legal means available for appeals and complaints."

A Western diplomat said the international community was not interested in revisiting a power-sharing deal to end the unrest and stalemate, as happened a decade ago. That avenue was "not an option", the diplomat said.

"If you have evidence that the election was rigged, produce it," he said.

"Most of the stuff NASA are alleging is not accurate."

Initially, the coalition charged the electoral server had been hacked, and produced 50 pages of computer logs that security experts said were inconclusive at best.

They later said a secret source within the electoral board had passed them the true election results. That two-page document was debunked by the election commission, which pointed out basic mathematical errors.

You are dishonest.
And that's dishonourable
