Four U.N. human rights experts have called on China to immediately release Nobel Peace Prize laureate Liu Xiaobo.
The independent U.N.-appointed investigators say Liu is "a courageous human rights defender who has continuously and peacefully advocated for greater respect for human rights" in China
In a statement Monday they called on China to release Liu and "all persons detained for peacefully exercising their right to freedom of expression."
The democracy campaigner was sentenced to 11 years in prison last year for "inciting subversion of state power." The Nobel prize was announced on Friday.
The four U.N. experts are Frank La Rue, El Hadji Malick Sow, Margaret Sekaggya and Gabriela Knaul. They examine issues ranging from breaches of the right to free speech to arbitrary detention.
