Bosnian

ANYTIME IT SEEMS THAT THE MESS IN BOSNIA CANnot get any more complex, or deadly, it promptly does. Now food is being used as a weapon -- by Serbs and Croatians against Muslims, and by Muslims against themselves. And its use has started an internal feud among U.N. officials. Enraged by Serb blockades that prevented U.N. food convoys from reaching 100,000 Muslims trapped in besieged towns in eastern Bosnia, Muslim President Alija Izetbegovic stopped distribution of U.N. relief supplies to the 380,000 residents of Sarajevo -- in effect pushing them into a sympathetic hunger strike. In disgust at the intransigence on all sides, Sadako Ogata, the U.N. High Commissioner for Refugees, ordered a stop to all U.N. relief efforts until they can be carried out without hindrance. U.N. Secretary-General Boutros Boutros-Ghali promptly rebuked her and ordered shipments resumed, remarking, "I am supposed to direct this operation." At week's end a 10-truck convoy had been waved through by Serbs, but still could not get to besieged Gorazde over shell- cratered roads. Then Bosnian Serbs and Izetbegovic found separate, and rather fanciful, reasons to boycott a new round of peace negotiations that were supposed to begin Friday at U.N. headquarters in New York City, though U.N. officials nursed hopes they will show up this week. For relief from daily bloodshed, meanwhile, some Sarajevans turned to the first movie to open there in many months: Terminator 2.
