Jailed Chinese dissident Liu Xiaobo has been named the winner of the 2010 Nobel Peace Prize.
The award, announced in Norway's capital Oslo, is certain to anger Beijing, which had earlier warned against the move.
Ahead of the announcement, Norwegian Nobel Committee president Thorbjoern Jagland told local television he knew he would have to defend the choice.
Mr Liu, 54, was jailed for 11 years on Christmas Day last year for drafting Charter 08, which called for multiparty democracy and respect for human rights in China.
Norwegian media also reports that BBC and CNN went black in China as the peace prize was announced. The Chinese embassy in Norway went into complete lockdown. Not even the mailman could get inside. There's been army of reporters outside the gates.
