Nairobi:?Nairobi Uhuru Kenyatta's vow to unite Kenya during his second term as President was dashed hours later by opposition leader Raila Odinga, who made a veiled reference to the coup in Zimbabwe and said he would be inaugurated next month.
Tens of thousands of people gathered at Nairobi's Kasarani stadium on Tuesday to watch Kenyatta's?lavish inauguration ceremony, attended by several African heads of state.
"I ask you to pledge to reject the politics of division," Kenyatta said in his address.
Shortly afterwards, Odinga told an opposition rally in Nairobi he would hold his own inauguration on December 12.
"We are inaugurating our people's assembly and that people's assembly is the one that will inaugurate me," Odinga said.
"We will be sworn in like [Zimbabwe's Emmerson] Mnangagwa and we will walk hand in hand with the constitution," he said.
Kenya's political crisis erupted after the Supreme Court threw out the results of an August election - won by Kenyatta - due to irregularities. A re-run election was held on October 26 and again won by Kenyatta - by a huge margin - after Odinga boycotted it and called it a "sham".
Odinga made his comments at a "memorial" service for alleged victims of police brutality, which the opposition planned to coincide with Kenyatta's inauguration.
The memorial event was the target of a police crackdown, the opposition said, with authorities reportedly firing tear gas and live bullets. An eye-witness said she had seen a young boy shot, but police said they knew nothing about it.
Odinga's National Super Alliance (NASA) coalition said in a statement that the roads out of several Nairobi slums where they have a large support base had been blocked by water cannon and armoured vehicles.
Odinga's convoy was itself teargassed on Tuesday and his supporters charged.
At the inauguration?Kenyatta did his best to paint a picture of a country moving beyond that divide.
"The elections are now firmly behind us ... I will devote my time and energy to build bridges," he told a rapturous crowd of around 60,000 supporters as he was sworn in for a second, five-year term.
But, he warned, Kenyans needed to "free ourselves from the baggage of past grievances, and ... keep to the rule of law".
Such words may ring hollow to citizens accustomed to the government ignoring reports on corruption from the country's auditor-general and documentation of hundreds of extrajudicial police killings every year from human rights groups.
Last year, Kenyatta angered many Kenyans by saying he wanted to tackle corruption but his "hands are tied". His government has also promised to improve police accountability, but an independent watchdog has managed to convict only two officers of murder despite thousands of brutality complaints.
On Tuesday, at least one Odinga supporter was killed and three others were injured. Some witnesses said the man had been shot by the police.
A statement from Odinga said five people were shot, including his daughter's driver.
Television stations KTN and NTV reported that a 7-year-old boy was hit by a stray bullet while playing on the balcony of a house near the site of a planned opposition prayer meeting.
"When I came home, I did not know it was my child who had been killed. Police were passing by shooting," Peter Mutuku, the boy's father, was quoted saying on NTV.
Police could not immediately be reached for comment.
Less than an hour after Kenyatta spoke, Kenyan national television carried pictures of riot police swinging clubs at civilians with their hands up.
"I didn't hear him say a single word on corruption and how he's going to fight it. I didn't hear anything on justice," said prominent anti-corruption campaigner Boniface Mwangi. "When he says that there's the rule of law, his actions and the actions of his government show there's no rule of law."
Kenyatta won a repeat presidential election on October 26 that was boycotted by Odinga, who said it would not be free and fair. The Supreme Court nullified the first presidential election, in August, over irregularities.
Supporters of Kenyatta - who won the October poll with 98 per cent of the vote after Odinga's boycott - want the opposition to engage in talks and move on.
"I'm sure Uhuru will be able to bring people together and unite them so we can all work for the country," said Eunice Jerobon, a trader who travelled overnight from the Rift Valley town of Kapsabet for the inauguration.
But Odinga's supporters see such talk of unity as tantamount to surrender. Many of them are drawn from poorer parts of the country, and feel angered because they say they are locked out of power and the patronage it brings.
Political arguments often have ethnic undercurrents, with Odinga's supporters pointing out that three of the country's four presidents have come from one ethnic group, the Kikuyu, although the country has 44 recognised groups.
Odinga accuses the ruling party of stealing the election, overseeing rampant corruption, directing abuse by the security forces and neglecting vast swathes of the country, including Odinga's heartland in the west.
"This election of October 26 is fake. We do not recognise it," Odinga told supporters from the rooftop of a car. "On December?12, we will have an assembly that will swear me in."
More than 70 people have been killed in political violence this election season, mostly by the police.
Riot police sealed off the scene of the rally in the morning, and fired teargas at residents, trying to prevent a crowd from gathering, as a helicopter hovered overhead. Roads were blocked by burning tyres, rocks and uprooted billboards.
In his speech, Kenyatta promised to raise living standards by increasing jobs, home ownership, electricity connections and health insurance coverage.
He also said all Africans would now get visas on arrival in Kenya, and members of the East African community could own property, work and live in Kenya, adding "to underscore Kenya's commitment to pan Africanism, this shall not be done on the basis of reciprocity".
