On July 14, 2017, a user on Twitter shared a video of what appears to be a broken or gashed wrist, claiming that it depicts: “Al Qaeda affiliated and US/UK funded ‘White helmets’ showing one of their tricks they use on gullible Western audience.”
This video has since been re-posted under a similar title on YouTube.
This claim is false.
This video is from an effects artist named Amanda Prescott.
An older posting of this video from December 25, 2016 can be seen under the Portugese title, “Mulher cortando o braço !!” This translates to, “Woman cutting her arm !!”
In this video, the watermark @AmandaPrescottFX can be seen at the top.
