Violence between ethnic groups has continued in areas of Kenya, fuelled by the killing of opposition MP Mugabe Were in the capital, Nairobi.
In the Nairobi slum district of Kibera, members of President Mwai Kibaki's Kikuyu community were attacked in apparent revenge for the MP's death.
At least four people died in Kibera, where there are reports of people being hacked to death or trapped in buildings and burned alive.
In the Rift Valley town of Naivasha, mobs of people from the Kikuyu group have been roaming the streets armed with machetes and guns.
Mobs have set fire to homes and businesses believed to belong to Luos, and have taken personal property into the street to be burned.
Police fired tear gas and rubber bullets from helicopters to disperse the crowds, but have been unable to control the violence and looting.
At least 800 people have now died across Kenya, in violence stemming from the disputed elections last month in which President Mwai Kibaki, a Kikuyu, was declared the winner.
