Serbian Prime Minister Aleksandar Vucic and other officials were forced to flee the memorial center in Potocari, Bosnia-Herzegovina, as an angry crowd threw stones and bottles on July 11. Vucic had come to attend the 20th anniversary commemorations of the Srebrenica massacre of some 8,000 Bosnian Muslim men and boys. Serbia and Russia have opposed calling the Srebrenica massacre a genocide, despite a UN ruling labeling it as such. (RFE/RL's Balkan Service)
