Citizens in Yugoslavia have escalated their campaign to oust Slobodan Milosevic. They’ve issued an ultimatum for him to step down as president and are staging massive protests, largely ignoring police. Angry crowds marched on the parliament building in Belgrade today. Some tried to fight their way inside. They were driven back by police who fired tear gas. But in some places, the crowds have been too big for police to even try to stop. In one town, protesters used a front-end loader to push aside sand trucks that police had set up as barricades. A Belgrade rally set for today will coincide with the ultimatum deadline. An opposition leader says if Milosevic doesn’t step aside, quote, “a flame will engulf the whole of Belgrade.” A Yugoslav judge, meantime, says there will have to be all new elections. He has nullified the elections that took place last week.
