A Bosnian woman and her baby arrive in Vienna, Austria, Friday with a group of 160 refugees from the war-torn republic of Bosnia-Herzegovina. Viennese officials are having difficulty finding space to house the refugees. Serb leader Radovan Karadzic on Friday offered a cease-fire and for the first time offered to let the United Nations monitor his forces. A U.N. spokesman called the proposal "encouraging" and said about 1,000 peacekeepers were ready to go to Sarajevo if a truce were called. But the fighting continued, and Croatia's Zagreb radio reported Friday night that 21 people were killed and 161 wounded in Bosnia-Herzegovina in the past 24 hours.
