Uighurs are sending out messages on social media video app Tiktok showing family members who have gone missing, in their latest attempt to raise awareness about the estimated 1 million Uighurs who have been detained in camps that have sprung up across China’s Xinjiang region. The videos, many of which are over eery music, show images of missing people, with a photograph or video of the person posting the clip superimposed over the top. Many of those posting the videos are crying.
