Cambodia bans Mia

Actress Mia Farrow has been barred from holding a ceremony at a Khmer Rouge prison as part of a campaign to pressure China to end abuses in Darfur. The American actress has started a torch relay through countries that have suffered genocides to draw attention to China's close ties with Sudan, as Beijing prepares to host the Games.

The campaign aims to push Beijing to pressure Sudan into ending the violence in Darfur, where the United Nations estimates that at least 200,000 people have died in five years of war, famine and disease.
