China is murdering members of the Falun Gong spiritual group and harvesting their organs for transplant, a panel of lawyers and experts said on Monday as they invited further investigations into a potential genocide.

Members said they had heard clear evidence forced organ harvesting had taken place over at least 20 years in a final judgment from the China Tribunal, an independent panel set up by a campaign group to examine the issue.

Beijing has repeatedly denied accusations by human rights researchers and scholars that it forcibly takes organs from prisoners of conscience and said it stopped using organs from executed prisoners in 2015.
