NAIROBI (Reuters) - Kenyan police fired tear gas and water cannon on Monday to disperse hundreds of people protesting at alleged bias in the country's electoral commission, and at least one person died in the disturbances.

The next presidential and parliamentary polls in Kenya, East Africa's largest economy, are not due until August 2017 but politicians are already trying to galvanise supporters in a country long prone to political strife. Violence erupted after the 2007 vote and the opposition disputed the outcome in 2013.
