Natural Sound Hundreds of demonstrators sympathetic to Yugoslavia have been burning cars and throwing fire bombs at the U-S Embassy in the Macedonian capital, Skopje. The trouble came only hours after the prime minister expressed concern over rising anti-NATO sentiment in Macedonia. In the capital, more than 2,000 demonstrators chanting "NATO out of Macedonia" threw stones, broke windows and hurled gasoline bombs at the U-S Embassy. A few hundred of the protesters tried to gather outside the embassies of NATO allies France, Britain and Germany. Police drove them away with several rounds of tear gas, creating loud booming noises that some media reports initially said were explosions. Three cars were burned as protesters tried to storm the U-S embassy. But riot police dispersed them, a fire engine extinguished the blaze and embassy staff were reportedly unharmed. Macedonia borders Yugoslavia, where NATO have staged airstrikes for two nights to try to force Yugoslavia to make peace with tits ethnic Albanian separatists in Kosovo province. Macedonia has supported the NATO operation, but its Serbian minority is sympathetic to Yugoslavia. Many Macedonians also dislike the growing NATO presence in the country. Earlier, the demonstrators marched to a hotel housing international officials who were monitoring peace in Kosovo until they evacuated last week. Waving flags of Yugoslavia and Macedonia, the protesters damaged a number of vehicles before heading to the U-S Embassy. Macedonian officials fear an influx of refugees from the Kosovo conflict will inflame tensions and overburden resources. The three border posts with Yugoslavia were open on Thursday, but saw little traffic. Macedonia says it already has 20 thousand refugees from Kosovo and cannot handle any more.
