SERBIAN BLOCKADE HINDERING THE U.N.
A fuel shortage resulting from blockades by nationalist Serbs has virtually paralyzed United Nations military and aid operations in the most vulnerable areas of this war-torn country, United Nations officials said today. Although the Bosnian Serbs have sporadically permitted food to enter some encircled Muslim enclaves in recent days, they are barring trucks carrying aviation or diesel fuel, said a spokesman for the United Nations peacekeeping force here, Lieut. Col. Jan-Dirk von Merveldt.
