ABUJA, Nigeria -- Nigeria's President Goodluck Jonathan urged his nation to vote peacefully and accept the results of today's presidential elections, which analysts said will be the most tightly contested in the history of Africa's richest nation and its largest democracy.
"No political ambition can justify violence or the shedding of the blood of our people," Jonathan, who is running for re-election, said Friday in a televised broadcast.
In a country steeped in a history of coups, bloodshed caused by politics, ethnicity, land disputes and, lately, the Boko Haram Islamic uprising, the election is important as Africa's most populous nation consolidates its democracy.
"It's just healthy that they approach this as an exercise of the rights of Nigerians to choose their government and not as a war," said Mohammed Ibn Chambas, the United Nations secretary-general's special envoy to West Africa.
Nigeria's political landscape transformed when the main opposition parties formed a coalition two years ago and for the first time united behind one candidate, former military dictator Muhammadu Buhari, who is Jonathan's main challenger.
The election is only the eighth since independence from Britain in 1960 and the first ever to raise the possibility of a democratic transfer of power through the ballot box, a high-stakes contest in Africa's biggest oil producer where patronage and corruption are rife. No incumbent has ever lost an election.
It should be "cause for celebration," said Chidi Odinkalu, chairman of the National Human Rights Commission. But he noted it has spawned "the most extraordinary form of hate speech, incendiary vituperation, ethnic bating --all the things you are not supposed to do."
His state-sponsored but independent organization reported at least 58 killings by Feb. 13, and there have been many more since then, Odinkalu said. He also complained that politicians have done little to dampen tensions.
Meanwhile, Nigeria's military announced it had destroyed the headquarters of Boko Haram's self-declared caliphate, or state ruled by Islamic law, in fighting Friday that left several extremists dead. It said the recapture of the northeastern town of Gwoza cleared insurgents from strongholds in all three northeastern states, which seems unlikely. There was no way to verify the report.
Critics of Jonathan have said recent military victories after months of ceding territory to the Islamic extremists are a ploy to win votes -- a charge the presidential campaign denies.
"Wage Peace Not War" is a campaign long promoted by the National Orientation Agency, which is working with bloggers and other social media popular among millions of Nigerians, according its director general, Mike Omeri. The idea is to "create a lot of buzz" and build "a community of people that will be driven by a passion for peace."
Entertainment star and musician 2Face Idibia wrote a song aimed at young voters called "Vote not Fight: Election no be war" in Nigerian colloquial English.
But some people are so fearful of election violence that they are leaving for a while, going as far as the United States and Canada. Flights are packed, with airlines turning away standby passengers this week at the international airport in Lagos.
Army chief Lt. Gen. Kenneth Minimah said he will not tolerate any disruptions, warning this week that "whoever wants to invoke or provoke violence will meet organized violence" from security forces.
Jonathan's party has governed since decades of military dictatorship ended in 1999. His insistence on running has caused many defections to the opposition by politicians who say Jonathan is breaking an unwritten party rule to rotate power between the mainly Christian south, where he is from, and the predominantly Muslim north that is Buhari's stronghold.
Buhari's loss to Jonathan in 2011 elections sparked riots in the north that killed more than 1,000 people, according to the human rights commission. A complaint before the International Criminal Court at The Hague accuses Buhari of instigating the violence, a charge the retired general denies.
Jonathan and Buhari signed peace pledges Thursday and urged their supporters to avoid violence.
Security forces are on high alert against electoral and Islamic extremist violence, and all Nigeria's land and sea borders have been closed as an extra precaution.
There are extra roadblocks in cities like Abuja, the capital, which has been rocked by three suicide bomb blasts in the past year that killed hundreds and were blamed on Boko Haram.
