"No sooner had Mengistu seized power than he unleashed an orgy of killing. Arms were given out to the Kebelles ('Urban Dwellers Associations') and a 'people's militia' was formed. Mengistu publicly urged it and the army to 'dispense revolutionary justice' and 'liquidate counter revolutionaries'. Revolutionary justice meant summary killing, without trial, of suspected enemies of the regime."
