Olympics 'worsening China rights'

China's human rights record is getting worse, not better, because of the Beijing Olympics, a rights group says.

According to Amnesty International, China is clamping down on dissent in a bid to portray a stable and harmonious image ahead of the Games in August.

It urged the International Olympic Committee (IOC) and world leaders to speak out against abuses, including China's handling of protests in Tibet.

US President George W Bush is facing calls to boycott the Games' opening.
