Chinese state media have released a video appearing to show a Uighur musician previously reported to have died in a detention camp.

The video, dated 10 February, features a man said to be Abdurehim Heyit stating that he is in "good health".

Turkey earlier called on China to close the camps following reports of his death. Up to a million Uighurs are reportedly being detained.

Some Uighurs have questioned the video's authenticity.

Nury Turkel, chairman of the US-based Uyghur Human Rights Project, told the BBC that some aspects of the video were "suspicious".
