The key point for the narrative that's missing in western news reports I've read so far: do not believe for a second that these riots and what's happening in Zimbabwe are unrelated. There are very, very sinister scenarios doing the rounds. There is an increasing risk this violence will spread to white-black violence too.
To assure some readers here, I've ramped up my own level of security: I've suspended all my volunteering actions in townships and am arranging secure transport to and from university.
