Kofi Annan arrives in Kenya as mediator

Police fired tear gas to break up pro-government demonstrations in Kenya today in advance of the arrival of former UN chief Kofi Annan on a peacemaking mission.

Mr Annan, who will hold talks with disputed president Mwai Kibaki and his main rival Raila Odinga, is seen as the main hope for getting a settlement that will end weeks of violence in which more than 600 people have died.
