BONN (Reuters) - Delegates from the Federal Republic of Yugoslavia left a peace conference on Bosnia in Bonn on Wednesday refusing to sign a final declaration to be released at the end of the talks. The Yugoslav delegation head Dragomir Vucicevic told Reuters: "We are leaving now. We will not sign." He added that they would not sign the declaration on peace implementation in Bosnia because it also contained a reference to Kosovo, the Serbian and Yugoslav province which is the subject of a dispute with ethnic Albanians living there. Vucicevic said Kosovo was a domestic issue for Yugoslavia and did not concern the international community. It was not immediately clear whether the Bosnian Serb delegation would agree to the final document. Its representatives had earlier walked out in solidarity with the Yugoslav position. The declaration was due to be announced by the international community after the scheduled end of talks around 1200 GMT.
