'Liu Xiaobo must be freed' - Nobel prize committee
The chairman of the Nobel prize committee has called for the immediate release of jailed Chinese dissident Liu Xiaobo, winner of the 2010 peace prize.
There were two standing ovations at the ceremony in Oslo for Mr Liu, who was represented only by an empty chair.
China has been angered by the award and has waged a campaign in recent weeks to discredit it.
