 In response, agitated protesters shouted slurs such as "pigs", "bandits", "Gestapo", "murderers" and "servants of Brezhnev".An unsuccessful attempt was made at building a barricade, but the government units were able to pass through and dispersed the first group with tear gas.When the demonstrators regrouped and formed a second wave, ZOMO opened fire and wittingly murdered 2 men.
