Several other missiles struck Cacak, an industrial town 60 miles south of Belgrade that has been attacked repeatedly since the air campaign began. NATO warplanes attacked chemical plants in Pancevo, just northeast of Belgrade. Yugoslav media said the attack sent up a mammoth plume of phosgene and chlorine, both toxic gases, but that favorable winds kept the fumes from reaching the city. Tanjug reported that 50 people were overcome by the fumes. The alliance also hit oil refineries near Novi Sad and Smederevo in its ongoing attack on oil facilities.
Oil is a critical factor.
The 19-member alliance has not yet agreed on how to stop oil from reaching Yugoslavia from outside, via tankers or overland deliveries, according to State Department spokesman James Rubin. The United States wants to block deliveries of oil by sea, but the proposal has run into opposition from France and other NATO members. Serbian forces did not yet appear to be running out of fuel, maintaining 400 tanks and more than 40,000 soldiers in Kosovo. Also Monday, U.S. officials gave their most detailed account yet of the airstrikes last Wednesday that accidentally killed scores of Kosovo refugees in a convoy. NATO pilots attacked the military vehicles at the head of the convoy when it was discovered near the village of Djakovica, where several homes had been set on fire, according to Air Force Brig.
