The Xinjiang Police Files
I'm always surprised how little interest there seems to be from the international muslim community in the Xinjiang situation, given that at least parts of it really blow up over even minor anti-Islam actions by single individuals quite regularly. The actions of China seem at least in part aimed at extinguishing Islam as a religion in the region, which would seem far worse than some person drawing a cartoon.
But maybe any reactions just don't make mainstream news.
