The social media campaign, launched Tuesday under the hashtag #MeTooUyghur, follows the release of a state media video showing famed Uyghur musician Abdurehim Heyit, who many believed had died in custody.
“China, show us their videos if they are alive!” Halmurat Harri, a Finland-based Uyghur activist, wrote on Twitter. He urged the Chinese regime to also release videos to prove that others believed detained are in good health amid reports of neglectful and sometimes brutal conditions in the camps.
Beijing faces growing international pressure as it continues to use the excuse of fighting terrorism and radicalization to persecute Uyghur Muslims.
Many Uyghurs outside of China have said they are unable to contact relatives still in Xinjiang. Fearing that their loved ones have been ensnared by the security dragnet, they say they do not even know whether their family members are dead or alive.
The mere act of communicating with someone overseas could spur detention, Uyghurs say, and as a result many of their relatives in China have blocked them on social media. On Twitter, Uyghurs abroad posted photos of themselves holding up images of their missing parents, children and siblings.
If they are still alive, the posts said, the Chinese government should release videos of them too.
