Saying "We don't want to fight. . . . We want peace as soon as possible,"Bosnian Serb leader Radovan Karadic released 130 more U.N. hostages, leaving only 14 still captive. Karadic says he is releasing the peacekeepers because of NATO promises to renounce bombing raids. AlthoughNATO officials deny making any such promises, they also say that no bombing will occur while the Serbs still hold U.N. forces. The Bosnian Serb leader will soon have more than NATO to contend with. Even as a buscarrying 26 of the hostagescrossed into Serbia, the Bosnian government stepped up the heat on Karadic's troops around Sarajevo. Some 15,000 Bosnian Muslim troops massed north of the beleaguered city of Sarajevo in what many believe is a precursor to a final assault to cut Serb supply routes and end the siege of the city.
