(bbc) Thirty Kenyans including many children have been burned to death in a church, after seeking refuge from the mounting violence over last week's elections. A mob set fire to the church in Eldoret where many people from President Mwai Kibaki's Kikuyu tribe were sheltering. The Kenyan government has accused supporters of opposition leader Raila Odinga of carrying out "ethnic cleansing" against the Kikuyu. Both President Kibaki and Mr Odinga have called for the killing to stop. An estimated 250 people have died in the violence that erupted following the controversial re-election of President Kibaki, according to police and journalists across the country
