A UN human rights panel has asked China to disclose the whereabouts of more than 300 Tibetan monks who disappeared after being arrested by the Chinese security forces in April. More than 300 monks of the Ngaba Kirti Monastery,located in Ngaba County, Sichuan Province, were allegedly arrested by the Chinese People's Armed Police on April 21. According to UN Working Group on Enforced or Involuntary Disappearances, until now, their whereabouts are unknown and repeated efforts to find where they are detained proved vain. The Working Group which includes five independent human rights experts is chaired by Jeremy Sarkin of South Africa. In a scathing indictment on the forced or voluntary disappearance of Tibetan monks, who are kept incommunicado, it said Beijing must provide full information.
