2 (MP) of Kenya have been killed.Annan is in Kenya for peace meditiation mission.To avoid killings what to do?

My worry is Koffi Annan he will not be able to achieve the goal at all. The killing macre will carry on daily unless Kibaki to stepped down immediately and the new government formed ASAP by Raila Odinga or the new election to be conducted and financed by the USA and European countries rather than waiting for the more killings daily.
