If you're active on social media you may have noticed many users turning their Instagram profile pictures blue, and you might be wondering why. It all started on June 3rd when peaceful protester Mohammed Hashim Mattar was killed during a demonstration against Sudan's Rapid Support Forces' (RSF) military crackdown.
