Kenyan police have killed a man in the western city of Kisumu during a protest by the opposition, an eyewitness has told the BBC.
A local hospital said that a body had been brought in, but the cause of death had not been confirmed.
This is the fourth week of protests over the electoral commission.
Last week, there were complaints of police brutality as officers were pictured assaulting demonstrators in the capital, Nairobi.
The opposition Cord alliance wants the current members of the electoral commission to resign ahead of next year’s presidential election.
Cord is complaining that they are biased in favour of the governing Jubilee coalition and want it replaced by a neutral body, the BBC’s Anne Soy reports from Nairobi.
Several other places have also been caught up in the demonstrations including the coastal city of Mombasa, where police fired tear gas to prevent protesters from gathering.
In Nairobi, there was a heavy police presence to stop people joining the demonstrations.
The opposition says that one of its senators leading protests in the western town of Kakamega has been arrested.
