The cases against Mr. Kenyatta, Mr. Ruto, former head of civil service Francis Muthaura, and radio journalist Joshua Sang were announced in January this year.
Drawing on documents and eyewitness accounts from victims and participants, the ICC's main prosecutor Luis Moreno Ocampo argues that these four men organized mob violence in the Central, Rift Valley, and Western provinces of Kenya, violence that sparked off after President Mwai Kibaki was declared the winner of the Dec. 2007 elections. In Western and Rift Valley provinces, mobs of ethnic Luo and Kalenjin supporters targeted ethnic Kikuyu neighbors who were presumed to have voted for President Kibaki, a Kikuyu. In Central province and in the town of Naivasha, Kikuyu mobs returned the favor, targeting the Luo and Kalenjin community who were presumed to have supported Ruto, a Kalenjin, and Prime Minister Raila Odinga, a Luo.
The violence raged for two months, before a mediation team led by Kofi Annan negotiated a new coalition government that included all the major players. Although those regions affected by the violence have since recovered, efforts to seek justice for the victims through a Kenyan-led tribunal have been rejected twice by parliament, a move that prompted the ICC to take up the case instead.
