Kenyan taxi drivers working for Uber are demonstrating outside the company’s office in the capital, Nairobi.
They are complaining that Uber has reduced its prices too much.
The BBC’s Emmanuel Igunza is there and says that there are around 150 drivers protesting.
People can hail Uber taxis using an app on their smartphone and the service has been accused of undermining more traditional taxi operators in cities around the world.
Last week, Uber said it was lowering its prices in Nairobi in response to competition from other companies.
