NATO's massive attack on a Serb-held air base Monday seemed to have little impact as Serbs today set northwest Bosnian villages on fire, sending civilians fleeing for their lives. They also fired missiles at two NATO jets flying over Serb-held areas (the missiles missed their targets). And Radovan Karadzic, leader of the Bosnian Serbs, promised to unleash awave of retaliation against NATO and its members. "We will determine the time and the target of the revenge ourselves, but we will definitely make sure that it is painful for NATO nations," Karadzic told Bosnian Serb television. Even Bosnian Prime Minister Haris Silajdzic questioned the value of NATO's attack, which destroyed airfields but left intact the artillery batteries responsible for the destruction around Bihac.TIME Central Europe Bureau Chief James Graff, stationed in Sarajevo, characterizes the mood against the peacekeeping forces as one of "cold contempt." NATO and UN officials, stunned by the Serbs resilience, have authorized another attack for tomorrow morning, Graff has learned. The targets this time: launch points for surface-to-air missiles in the northwest, Graff says.Post your opinion on theInternationalbulletin board.
