President Mwai Kibaki's government has accused rival Raila Odinga's party of unleashing 'genocide' in Kenya.
A statement from the government said 'it is becoming clear that these well-organised acts of genocide and ethnic cleansing were well planned, financed and rehearsed by Orange Democratic Movement leaders prior to the general elections'.
Mr Odinga's party reacted by saying that the government was also 'bordering on genocide' by ordering police to shoot protestors enraged by Mr Kibaki's victory in 27 December polls, which international observers said fell short of democratic standards.
Mr Odinga also said he plans to go ahead with tomorrow's banned rally despite pleas for an end to the post election violence, in which up to 300 people have died.
