At least five people were killed on Friday as Kenyan police tried to disperse supporters accompanying opposition leader Raila Odinga from the airport to central Nairobi, police said.
Police fired tear gas at the convoy in which Odinga was traveling and used water cannon as they tried to stop it reaching the capitalโs main business district.
Some protesters threw stones at police. Two vehicles, including a police truck, were set on fire.
A Reuters photographer saw two bodies with gunshot wounds as police and protesters fought on one of the main roads leading to the business district.
Police said five people were stoned to death by angry mobs after they were caught stealing and denied they had used excessive force against the opposition supporters.
โThese incidences occurred before the police arrived at the various scenes,โ the police service said in a statement.
Police retreated several times along the route after the protesters were unmoved by the teargas and water cannon spray. They finally held their ground near the cityโs main park, where Odinga, just returned from the United States, intended to address a rally that had been banned.
He blamed President Uhuru Kenyatta for the violence.
โMy anger is with that guy called Uhuru Kenyatta. I went abroadโฆ After you welcomed me well, he sent policemen to teargas you, to beat my people, to fire bullets at them. Isnโt this barbaric?,โ he told his supporters after driving to safety.
Odinga has called for a โNational Resistance Movementโ to protest against the outcome of a repeat presidential election last month which saw Kenyatta win a second, five-year term with 98 percent of the vote after Odinga boycotted the contest. Only 39 percent of registered voters took part.
The repeat poll was ordered by the Supreme Court after it annulled the results of the August election, won by Kenyatta, over procedural irregularities.
The court will rule on Monday on cases that seek to nullify the rerun election.
The political crisis has stirred fears for the stability of Kenya, a regional hub for trade, diplomacy and security.
Earlier on Friday, demonstrators threw up burning barricades on Mombasa Road, the highway that links Nairobiโs downtown business district and the airport.
Despite a partial police ban on protests in the capital, hundreds of people had gathered in the morning near Jomo Kenyatta International Airport to await Odingaโs return. Police fired into the air to disperse them.
Once Odinga landed, motorcycle taxi drivers and people on foot shouted their support as the motorcade, which included lawmakers from Odingaโs opposition coalition, began moving toward central Nairobi.
Dozens of international flights depart and arrive daily at Nairobiโs main airport. The national airport authority said on Twitter just before midday that operations were running normally.
Kenya Airways said it had been โimpactedโ by the disruptions around the airport and offered to book travelers who missed their flights on subsequent ones.
Kenyaโs prolonged election season has disrupted its economy. Human rights groups say at least 66 people have died in bloodshed surrounding the two elections.
Ahead of Mondayโs Supreme Court ruling, Kenya Airwaysโ chairman told an investor briefing on Friday: โHopefully we donโt have another presidential election so we can get on with life.โ
