A Japanese manga comic of a Uighur woman's story of survival in a detention centre has been viewed over 2.5million times since it was launched in April.

Entitled "What has happened to me", the story's popularity comes amid the release of two tranches of leaked documents, revealing the inner workings of the Chinese government-run camps in Xinjiang, which have detained about a million people without trial.

Readers of the comic have commented that the manga story has given them a greater understanding of the plight faced by pro-democracy protesters in Hong Kong.
