The UN General Assembly voted Thursday to establish an annual day of remembrance for the 1995 Srebrenica genocide, despite furious opposition from Bosnian Serbs and Serbia.
The resolution written by Germany and Rwanda -- countries synonymous with genocide in the 20th century -- received 84 votes in favor, 19 against with 68 abstentions and makes July 11 "International Day of Remembrance of the Srebrenica Genocide."
"This resolution seeks to foster reconciliation, in the present and for the future," said Germany's ambassador to the UN Antje Leendertse.
Ahead of the vote, Serbian President Aleksandar Vucic warned the General Assembly that the move "will just open old wounds and that will create a complete political havoc."
But he said he did not deny the killings at Srebrenica, adding that he bowed his "head to all the victims of the conflict in Bosnia."
Following the vote, Vucic draped himself with his country's flag, before saying those behind the vote "wanted to stigmatize Serbian people -- they did not succeed."
Church bells rang out across Serbia on Thursday in protest. The Serbian Orthodox Church said it hoped the gesture would unite Serbs in "prayers, serenity, mutual solidarity and firmness in doing good, despite untrue and unjust accusations it faces at the UN."
Except Serbia, all of the former Yugoslav republics voted for the resolution.
Bosnian Serb leader Milorad Dodik, meanwhile, denied a genocide had even taken place in the Bosnian city and said that his administration would not recognize the UN resolution.
Bosnian Serb forces captured Srebrenica -- a UN-protected enclave at the time -- on July 11, 1995, a few months before the end of Bosnia's civil war, which saw approximately 100,000 people killed.
In the following days, Bosnian Serb forces killed around 8,000 Muslim men and teenagers -- a crime described as a genocide by the International Criminal Tribunal for the former Yugoslavia (ICTY) and the International Court of Justice.
The incident is considered the worst single atrocity in Europe since World War II.
In addition to establishing the memorial day, the resolution condemns "any denial" of the genocide and urges UN member countries to "preserve the established facts."
In a letter to other UN members, Germany and Rwanda described the vote as a "crucial opportunity."
- Threat to peace, security -
However, there has been a furious response from Serbia and the Bosnian Serb leadership.
In an attempt to defuse tensions, the authors of the resolution added -- at Montenegro's request -- that culpability for the genocide is "individualized and cannot be attributed to any ethnic, religious or other group or community as a whole."
That was not enough for Belgrade.
The Srebrenica Memorial Centre praised the UN resolution, calling it proof "we are not alone."
UN rights chief Volker Turk, and rights group Amnesty also welcomed the move.
But Human Rights Watch said it "leaves out any reference to the UN peacekeepers' dismal failure to protect thousands of Bosnian Muslim men and boys."
Russia's UN ambassador, Vasily Nebenzia, said "if the goal of the sponsors was to divide the General Assembly... then they've succeeded brilliantly."
Moscow previously vetoed a UN Security Council resolution in 2015 condemning the "crime of genocide at Srebrenica."
Milorad Dodik, political leader in the Bosnian Serb entity -- where thousands of people demonstrated this April against the resolution -- said the Srebrenica genocide had been a "sham."
The European Union has responded strongly, with foreign affairs spokesman Peter Stano saying "there cannot be any denial" and "anyone trying to put it in doubt has no place in Europe."
Several EU nations including Greece, Cyprus and Slovakia abstained however.
For relatives of the victims of the massacre, the creation of a memorial day was an important step forward.
"Those who led their people into this position (of genocide denial) must accept the truth, so that we can all find peace and move on with our lives," said Kada Hotic, 79-year-old co-director of an association of Srebrenica mothers, who lost her son, husband and two brothers.
