US film-maker Steven Spielberg has abandoned his role in the Beijing Olympics and a host of prominent figures accused China of not doing enough to press its ally Sudan to end devastating violence in Darfur.

"Sudan's government bears the bulk of the responsibility for these ongoing crimes but the international community, and particularly China, should be doing more to end the continuing human suffering," Spielberg said in a statement on Tuesday.

"I have decided to formally announce the end of my involvement as one of the overseas artistic advisers to the opening and closing ceremonies of the Beijing Olympic Games."

We need more people like him to support the crime against people of Sudan.
