Uyghurs maintained that the attacks started after the night shift at around 12.30 a.m., when Han mobs stormed into Uyghur dormitories and started indiscriminate and unprovoked beatings [REF].
The rioting was sparked by allegations of sexual assault on Han women by Uyghurs, and rumours of an incident in which two female Han workers were sexually assaulted by six Uyghur co-workers at the factory, according to Voice of America [REF].
