Serb forces attacked an ethnic Albanian village in Kosovo Tuesday after residents ignored a warning to surrender weapons following an ambush on a Serb patrol, according to sources on both sides.

The Albanian-run Kosovo Information Center said the attack began Tuesday morning on the village of Tusus, about 40 miles southwest of Pristina. Smoke could be seen rising from four other villages in the area, near the border with Macedonia.The Kosovo Liberation Army is fighting for independence from Serbia, the main province of Yugoslavia. Yugoslav President Slobodan Milosevic has promised to discuss autonomy - favored by the Americans and Europeans - which he revoked in 1989.

But he has refused to grant independence, although Albanians outnumber Serbs in the province 9-1.

A source in the party of Kosovo's main ethnic Albanian politician, Ibrahim Rugova, told The Associated Press the attack began after villagers ignored a warning by Serb police to hand over their weapons or face attack.
