KENYAN police have tear-gassed opposition leader Raila Odinga’s convoy in the capital, Nairobi, as he spearheaded the biggest protest against President William Ruto’s government since it took office.
The protests have also spread to other cities, with a university student reportedly shot dead in Kisumu.
Mr Odinga accuses the government of being “illegitimate”, and of failing to tackle the high cost of living.
Mr Ruto has rejected the claims.
Kenya’s highest court upheld his victory in last year’s election, but Mr Odinga insists that the election was “stolen”.
He has been driving through Nairobi’s residential suburbs to rally his supporters and has vowed to organise weekly protests against the government.
It has caused many businesses to shut in the city, due to fears of looting. At least one person has been reportedly shot in the capital.
Running battles have taken place on the main Kenyatta Avenue between police and demonstrators, some of whom are throwing stones at the security officers.
Roads leading to key government buildings have been blocked and the president’s official residence sealed off.
In the western city of Kisumu, where Mr Odinga draws a fanatical following, riot police confronted protesters.
The university student died after being shot in the neck by police in the Maseno area of the city, Kenyan media reports.
Police said demonstrators threw stones and injured six officers, prompting security forces to fire live bullets.
