Junuary 12, Euromaidan rally in Kharkiv. There is no audio for this video but we see thugs called titushki throwing explosives at peaceful protestors who support Euromaidan. They have coordinators who help them to escape when protestors chase them down in order to prevent from more provocations. They often run behind the police lines to hide and seek protection.
