This appears to be related to the earlier post about riots in Moscow.
This is the description of the video according to Nina (Thank you!)
In Moscow’s region, Birulevo, Russians protest death of a guy who defended his fiance’s honour as she was being disrespectfully approached by a man of a seemingly Arabic appearance. Many of such men come to Moscow and St.Petersburg working menial jobs selling produce in the outside markets. As a result of it, one of such markets is being now attacked as the overall dislike of immigrants from former Soviet Islamic republics is on the rise.
