Russia slammed a draft UN resolution on the Srebrenica genocide as divisive Tuesday, and said it would present its own measure while the United Nations marks 20 years since the massacre.
Britain has circulated a draft text to the Security Council ahead of the 20th anniversary of Srebrenica to reflect on the UN's failure to prevent genocide.
Russian Deputy Ambassador Petr Iliichev told reporters that the British draft was "divisive" and focused too heavily on wrongdoings carried out by the Bosnian Serbs.
"It focuses on only one aspect," said Iliichev. "It was only one part of the conflict."
The council is expected to adopt a resolution on July 7, just days before Bosnia is to hold commemorations at the Srebrenica memorial to remember one of the darkest chapters of the 1992-1995 war.
But it remained unclear if the 15 members would come to agreement after Russia proposed to drop any mention of Srebrenica in the text and focus instead on the Dayton peace accord that ended the war, diplomats said.
About 8,000 Bosnian Muslim men and boys were slaughtered by ethnic Serb forces in July 1995 in what was the UN-protected enclave of Srebrenica.
It was Europe's worst atrocity since World War II and has been labeled a genocide by two international courts.
Bosnian Serb leaders have called on Russia, which was close to Serbia during the war, to veto the resolution, taking issue in particular with the use of the word "genocide" to describe the massacre.
In a letter to UN Secretary-General Ban Ki-moon, the Serb chairman of Bosnia's rotating presidency, Mladen Ivanic, called the resolution "anti-Serb because it fails to mention in any way the Serb victims of the Srebrenica region."
British Ambassador Matthew Rycroft said the resolution "will commemorate the victims of the Srebrenica genocide, and those who suffered on all sides in the war."
The British draft resolution will "encourage further steps towards reconciliation" and "affirm our determination to prevent genocide," he said.
Bosnia's 1992-1995 war claimed some 100,000 lives and left the country split into two-semi independent entities -- the Serbs' Republika Srpska and the Muslim-Croat Federation.
