Fighting flared yesterday in northern and southern Bosnia, pitting Serbs against Muslims and Muslims against Croats. Meanwhile, Bosnian Serbs voted on a peace plan they seem certain to reject.
   The defiance of Bosnian Serbs and the three way fighting underlined the complexity of bringing peace to this rugged state. A brutal 13-month war had destroyed its elaborate ethnic quiet, stitched together by centuries of co-existence.
   United States President Bill Clinton has dismissed this weekend’s Bosnian Serb referendum as a maneuver to buy time. He is expected to press reluctant Europeans for military action against Bosnia’s Serbs ff they do reject the apparently doomed Vance-Owen plan.
   Russian Foreign Minister Andrei Kozyev said after talks with international mediators yesterday that the Vance-Owen plan should be implemented regardless of the outcome of a referendum in Bosnia.
   The Vance-Owen plan would divide Bosnia-Herzegovina into 10 largely autonomous provinces, Muslims, Serbs and Croats would each dominate in three provinces, with the tenth, Sarajevo, jointly governed.
