The United Nations approved a resolution Thursday establishing an annual day to commemorate the 1995 genocide of more than 8,000 Bosnian Muslims by Bosnian Serbs, a move vehemently opposed by Serbs who fear it will brand them all as "genocidal" supporters of the mass killing. The vote in the 193-member General Assembly was 84-19 with 68 nations abstaining, a reflection of concerns among many countries about the impact of the vote on reconciliation efforts in deeply divided Bosnia.
